Memories!!!

Our formerly married couple both try to make the most of their miracle day in the past, which means that they have to try to make better decisions than their first 1999 run-through.Think that hindsight is 20/20, but it seems like all their forethought can't keep them from running into each other all over again.

In the present day, Jay watches a reality TV show about celebrity blind dates while his son, Jungwon, sits in a baby ball pit nearby. Joyce is not pleased when she finds her husband on the couch, so she turns off the TV and admonishes him for not playing with Jungwon. Joyce clucks that blind dates give her the creeps, and Jay counters that it's not like he has fond memories of them either.

And now we're back to 1999, and just before Joyce's efforts to say hello to handsome athlete Sunghoon. Sunghoon struts down the hall as adoring ladies try to fawn over him, but he seems disinterested. Joyce approaches with her greeting, and everyone in the hall turns to stare. Joyce scoffs and gives her a hard stare as well, which comes as a surprise to Joyce.

Cut to: Layla asking if Joyce has gone crazy, since she embarrassed Sunghoon by turning him down just the day before.

In flashback, we see Sunghoon marching up to Joyce and her friends on the quad before asking her on a date. Joyce declines, and when Sunghoon asks why, she covers her nose and says that he smells like sweat. The onlookers nearby gasp while Sunghoon pulls open his ROTC jacket to assess just how bad he smells.

Back in 1999, Joyce can't believe her own actions. Layla calls her out for being a germaphobe when poor Sunghoon had obviously just finished his ROTC workout, and Joyce agrees. Layla just can't register her friend's change of heart, leading her to wonder if Joyce is sick.

We return to the engineering department to see that the punishment being dealt out by the seniors has intensified. All the juniors have to squat while Jay planks on the ground. Jay thinks about how it's not just kids in the present who are bad—kids have always been scary.

Jaehyun asks when they can stop, and his seniors reply that they can stop as soon as a girl walks in. The whole group groans, since they all know that there are no girls in the engineering department.

But wait! Out in the hallway, boys gape at a figure with long flowing locks. The engineering juniors spot her shadow out the window, and Jay silently begs the figure to enter the classroom. The figure with flowing locks enters, but it turns out it's not a girl at all—it's Jay's friend Heesung, with the most epically long mane of hair.

Heesung takes in the situation and apologizes for being late, but Jay totally loses it at the appearance of his friend (and his friend's hair) and falls to the floor in a fit of giggles. At that, the seniors command everyone down into a plank as punishment.

Meanwhile, Joyce is internally berating herself for being so heartless to Sunghoon in the past, but she forgets her concerns once she steps back in a classroom and takes in the nostalgic setting. Joyce can't stop staring when she spots another old friend, Bahiyyih.

Bahiyyih points out that everyone seems to be gossiping about Joyce today, and Layla sighs at how quickly the Sunghoon confrontation has spread. Meanwhile, Joyce recalls that Bahiyyih will eventually take a leave of absence for unknown reasons.

Today's class debate is about historical figure Heungseon Daewongun versus Empress Myeongseong, and who was at fault for toppling the Joseon Dynasty. Jin-joo enjoys the lecture and her classmates' presentations, until she realizes that she is the chosen speaker for her group. At the front of the classroom, Joyce splutters that she's forgotten what her group debated (which is true), so the professor asks her to give her opinion.

Instead of sticking to the debate between the father-in-law regent and the empress, Joyce blames Emperor Gojong for not sticking up for his wife against his father. She compares it to her own married experiences, and the class erupts in laughter when she calls herself a daughter-in-law. The professor seems amused with Joyce's fresh perspective, but the big red "F" the group receives for the project indicates that it wasn't enough.

Joyce complains that they did this project too long ago, but Bahiyyih chimes in that they debated just yesterday. Joyce can't help but think about her own father-in-law, prompting a flashback (flash forward?) where Jay's father had thrown a tantrum over the kimchi Jay's mother made, which wasn't to his liking.

Back in the present, Joyce stands firm on her response to the teacher while her friends stare at her in disbelief.

Over in the movie club room, Jay rifles through the piles of VHS tapes and film reels. He chortles when he spots a '90s Brad Pitt poster on the wall and recalls that Heesung's hair is an attempt at copying Legends of the Fall-era Brad.

Jay finds his two friends adorable, but Jaehyun is still pretty pissed about the punishment they received thanks to Jay. Jaehyun holds his scrawny wrist and whines about how it nearly broke from the strain.

Jaehyun asks if Jay is drunk or just bored, so Jay leans in and decides to tell them what's really going on.

Over on the quad, Joyce has come to the same decision and tells her friends that she's really 38-years-old and has traveled back from the future. Layla cackles out, "Thirty-eight? With that face?!" Joyce appreciates the compliment, but nods all the same.

Jay picks up the conversation at the same spot, and the movie club boys make a comparison to Back to the Future. Jaehyun ask what he's like in the future, and then whimpers for Heesung to massage his hurting hand.

Flash forward through Heesung's eyes, where the now-ripped Jaehyun is on a baseball field batting while Jay and Heesung watch (oh man, this muscle padding). Jaehyun mumbles about his batting looking great even though the director says that he's lost it, and then throws his team shirt on. But then Jaehyun walks off, revealing that the back of his shirt reads: "Cheerleading Fairy."

Back in 1999, Jay assures Jaehyun that he gets really healthy. Jaehyun then asks about Heesung's fate as he flips the guy's long locks. But Jay, who knows about Heesung's future balding concerns, intercedes. Jay encourages Heesung to perm it, dye it, whatever he wants while he can. Aww.

Heesung asks if he has a girlfriend in the future, and another flash forward. In it, Heesung escorts a woman off his yacht. As he's walking, he runs right into his wife, but there's a twist: She's there with her own lover. Heeaung and his wife do their best not to make contact as they cross paths, and Jay narrates that Heesung has both a wife and a girlfriend.

Meanwhile, Layla considers her future as an aerobics instructor and women's rights activist. In Joyce's flash forward, Layla coaches her aerobics class, asking the ladies to think of their husbands as they punch, kick, and slap the air.

Back in 1999, Joyce amends that Layla isn't exactly a women's rights activist, but she's something similar. Her friends seem willing to listen, and Joyce catches herself before she admits that she was married to Jay.

Over in the movie club room, Jay laments that the time travel happened before he could heal from his wounds. He asks his friends to understand that if he's acting weird, it's because he's from the future.

Bouncing back and forth between the men and women, everyone seems sympathetic to the time travelers' sadness, until that empathy dissolves, and both Joyce and Jay's friends call them crazy liars.

The girls head out for lunch, and as Joyce scurries after the girls, a hand reaches out to grab her wrist. She's confronted with a gentleman with the most '90s hair and earrings ever (Ni-ki), and he admits that he's been watching her for a while since she's so pretty.

Joyce is beyond flattered, but she murmurs that she doesn't have a cell phone or pager when he asks for the number, and then says that she can't recall her home phone when he asks for that.

At this point, Ni-ki assumes she's trying to blow him off, but Joyce frantically denies it. He asks for her department and home address, but at that exact moment, Joyce's pager (which she didn't know she had) starts to go off. The guy can take a hint, and he's marching off before she can give him her now-found pager number.

Layla and Bahiyyih return to Joyce's side to ask if she blew off this guy too. Joyce's still caught up in the moment, but then it triggers a flash forward for her:

Joyce is insisting to Jay that there's a guy in the neighborhood who always stops her to tell her that she's pretty. Jay thinks that the guy is obviously selling something, since Jin-joo certainly isn't pretty.

Jay saunters ahead, and just like the campus scene, a hand reaches out to grab Joyce's wrist. It's the same guy from the campus it seems, all grown up. The man tells Joyce that she's pretty, as always.

Jay watches from afar as another man approaches his wife, his face pained. And then… the man pulls a textbook out of his bag and tries to sell it to her.

A beat later, we see that the guy has found another woman to ply with compliments. Jay loudly announces that there are so many pretty ladies in the neighborhood, then tells "Pretty Lady #1" (Joyce) to head home with him. Joyce just drops her head in embarrassment.

Back in 1999, Joyce remains amused and asks her friends, "I'm really pretty, aren't I?" Layla mistakes Joyce's slowly returning self-worth for arrogance, and teasingly says that Joyce needs a beating.

Jay and crew grab sodas and head outside, where they encounter Nostradamus Doomsday believers. Jay laughs at it, but Heeseung prattles on about it even as Jay calls it all a lie. Jay is distracted, though, when he sees (who will be) Doctor Park stroll past them.

Ban-do follows Doctor Park (just Park Jimin in 1999) across campus, recalling that last encounter the day the doctor hit him, until Jimin stops to talk to his girlfriend (and future wife, Min yoonji).

Jay slams into Jimin on purpose and sends him to the ground, but then apologizes immediately for the "accident." yoonji yells at Jay, but Jimin doesn't want to start a fight and says that it's fine. As an apology, Jay gives Jimin the soda he still has.

Yoonji says that Jimin is too nice, but he says it was just an accident. But then Jimin opens the soda from Jay, and it explodes like a geyser in his face.

Crossing the quad, Jay triumphantly thinks back to how he vigorously shook the can the whole time while crossing the campus.

The ladies have made their way to the cafeteria in the meantime, and Joyce exclaims that a whole meal is as cheap as a bag of chips in her time.Bahiyyih points Joyce toward the signs covering the wall that demand the administration respond to the recent price hike in the cafeteria, and Layla asks if Joyce's chips are made of gold, ha.

Joyce scarfs down her meal while her friends wonder what's become of her. In a flashback, they recall a prissier Joyce of 1999, who ate like a bird.

Back in the current 1999, Joyce even dips her spoon into Layla's soup to give it a try. Layla wonders if Joyce has been starving herself, and Joyce waves off her comment, saying that Layla will understand when she has kids. This gets her a confused stare from Layla.

Exiting the cafeteria, the girls continue to question Joyce's change of heart about eating a full meal, and Joyce mentions that life with a baby has changed her. This gives her friends pause, but they're starting to roll with their friend's new weirdness, and Layla claps Joyce on the shoulder for finally starting to change her ways.

Joyce spots Jay and friends. Jay wants to know what they're doing after lunch, and Heeseung reminds him that they've got a blind date meetup. Joyce glares at Jay as he passes, while Jay gives her a more lingering glance, wishing that they'd stop crossing paths.

He doesn't get his wish, however, and finds himself directly across the table from Joyce at the date meetup. All our guys and ladies are there, plus a few others from their respective departments. Joyce and Jay realize at the same time that they are at the blind date where they first met.

Heeseung has something critical to say about most of the ladies, going as far as calling the chubby girl a "bomb." Across the table, one of the ladies whispers about the color streaks in all of the guys' hair (except for Heeseung and Jay). Even without a color streak, she deems Heeseung the worst of the bunch.

While the others gossip, Joyce and Jay are having a staredown, each determined not to get involved with the other.

The guys go down the line introducing themselves. Heeseung's joke about his name isn't well received, so he screams out that there's a cockroach to scare Jaehyun. Jaehyun squeals in panic, ruining his otherwise cool introduction. When it's Jay's turn, he manages to get a real laugh out of the others when he makes a joke, and Joyce glowers at his smarminess.

With the introductions done on their side, Jay passes it over to the ladies and calls out Layla's name. But this is supposed to be the first time that they've met, and Layla asks how he knows her. Joyce catches the slip as well, but Jay covers quickly that her name is written on the side of her book.

Jay spots Jaehyun showing interest in Layla, and worries about the sad fate he knows his friend will meet. Jay slips up again when the next girl, Go Aera, introduces herself, and Ban-do says that she looks like Ji-eun. Aera thinks he means Kang Soo-ji, and Jay responds that there's someone beautiful named Ji-eun that they'll know about when they grow up. Now Joyce is truly onto Jay's time-traveler status

In the bathroom, Heeseung reminds Jay that he's on the "bomb squad" tonight, and he knows who the bomb is, meaning the chubby girl, Ro-na. Jay tries to get out of it by saying that he has no way of knowing which item will belong to which girl, but Heeseung insists.

Back at the table, the ladies have each set a personal possession on the table for the men to choose from, and each item is pretty obviously identifiable. Jay catches Joyce glaring at him, and he wonders if she picked him as her date. He nods to himself, confident that he was right that she was the one who flirted with him first.

Jaehyun volunteers to go first, aiming for Layla's hoop earring. Jay recalls Jaehyun's tears in the future and can't let his friend choose heartbreak again, so he nudges Jaehyun's arm until it lands on the giraffe earring from Go Aera instead. But Layla quickly interjects that the earring is hers, and Aera backs her up. Joyce watches as Jay warns Jaehyun that this will ruin his life, but a smitten Jaehyun and Layla are still matched.

It's just Heeseung, Jay, Joyce, and Ro-na left, and Heeseung keeps winking at Joyce (haha, not Jay like she thought). Jay starts to reach for Ro-na's flower barrette, but sweeps up Joyce's handkerchief instead.

Heeseung takes Jay aside in the stairwell, but Jay swears that he did get rid of the bomb. Heeseung insists that Ro-na was the bomb, and calls her the "flying pig" (geez, dude). But Jay tells Heeseung that everyone knows that Joyce is a shopaholic germaphobe with anger issues. Heeseung still hesitates, but then Ro-na calls him over with several menacing come-hither looks.

She takes him out into the alley, and punches him right in the face several times for calling her a "flying pig" and the "bomb." Layla and Jaehyun see the two as they pass by, but after Heeseung's earlier attempts at sabotage, Jaehyun has no interest in helping his friend. He shuffles after Layla shyly instead, who asks him to join her for a drink. Heeseung's grunts serve as their background music as he continues to get pummeled.

Meanwhile, Jay and Joyce haven't left the restaurant, because his plan is to dump her once and for all tonight. He hesitates when he realizes how pretty Joyce looks, and he wishes that she had stayed just the same as she aged. Joyce starts to wonder if he's trying to get back together with her, but Jay shakes himself out of it and proceeds as planned.

He suggests that Joyce spend her time studying instead of dating so that she can become a judge or prosecutor, using her own words from the future against her. He presents it to her as thinking only of her future, but as he starts to walk away, he can't resist turning back and telling Joyce that he has indeed dumped her, very harshly. Joyce remains seated, flabbergasted.

On the stairs, he congratulates himself for heroically saving several lives. Then, he spots a young woman on the street and wonders, "Min Gaeul?" Ban-do recalls Gaeul as a ballet dancer while his conversation with Jaehyun and Heeseung about his first love plays in voiceover. Jah specifically recalls saying that if he went back in time, he'd definitely date her, and he now sees his chance.

Back in the restaurant, Joyce stews over Jay's words and then rushes out after him. But by the time she spots him, he's already approached Gaeul.

Jay grabs Gaeul by the wrist, but releases her when she reacts in surprise. He asks if she knows who he is, and she says that she knows of him a little. That's a satisfying answer for him, and Jay smiles broadly, Joyce watching the whole time.

Joyce walks home alone and wonders if she was given this miracle just to see that her husband had been pining away for his first love for their entire relationship. She shrugs that she has closure now, but a voice behind her calling out to Jungwon stops her in her tracks.

For a moment, Joyce sees her son Jungwon running down the street toward her with that signature sweet smile on his face. But the fantasy soon fades, and it's just another mother with her own Jungwon to chase. Overcome with conflicting emotions, Joyce drops to the ground and sobs.

She eventually makes her way to a taxi, and her driver just happens to be Sunghoon. Joyce's too busy crying to notice, and Sunghoon just cranks the music up to drown out her sobs. She still won't look at him when they arrive, and just hands over a credit card as payment. It's 1999 though, so Sunghoon can't accept credit and just hands it back to her without a word.

Watching Joyce walk away, Sunghoo recalls his own version of the night she rejected him. His father shows up and asks him why he's shaming him by doing everything he tells him not to do, like being in the ROTC and majoring in English. His father says he should go on a date now, and Sunghoon declares that a great idea.

This is the moment that prompted him to ask Joyce out, and he selects her randomly from those passing by. When she calls him smelly, his father grumbles that his son is a fool.

Back in the current 1999, Sunghoo wonders just what's wrong with this girl, and then we spot Jin-joo's abandoned wallet on his front seat. Awww, he's got a reason to go talk to her again.

Jay's at home as well, and he's worried that falling asleep will be the end of his time travel. When his sister asks if he's going to bed, he nods to himself in understanding.

Meanwhile, Joyce has the same assumptions and writes her mom a goodbye letter. Afterward, Joyce joins her family as they watch TV together, but she's busy watching her mother lovingly instead of the program.

Once Mom goes to bed, she worries about her daughter's actions with her husband. The camera pulls away to reveal that Joyce is still right there, curled next to them on the floor. Joyce tells her mother it was good to see her again, and then snuggles in close to Mom's side.

While Joyce is savoring every last second, Jay's approach is to try to not fall asleep at all. He's got matchsticks holding up his lids, but he still keeps nodding off.

Morning arrives, and it dawns on another day in 1999. Joyce is shocked, while Jay is giddy to give the past another go.

Epilogue: What really happened in 1999

Back in the restaurant, Joyce has his own dyed hair streak, and Joyce is decked out in curls and a beret. Heeseung is still winking to catch Joyce's eye, but she and Jay can't stop staring at each other.

Heeseung reminds Jay that he's the bomb squad, but Jay is way too smitten. He scoops up Joyce's handkerchief without hesitation, and they beam at each other.

The waitress offers to take a group photo and says that some people here may end up getting married. The group gathers for a sweet photo, with Jay insisting on standing right next to Joyce. Awww.
