He didn't take the road home—instead, his car veered off in another direction.
Silently, Gu Lili followed at a distance, trailing him all the way to the upscale residential complex of Yunan Garden.
She didn't attempt to enter immediately, lacking an access card.
Left with no choice, she parked by the roadside outside the gates. When someone exited the complex, she stepped forward with a fabricated excuse and successfully drove in.
Her car crawled slowly through the grounds as she scanned the area for Long Yubei's vehicle.
She didn't spot him, but she did find his car.
A fleeting glimpse caught her eye—Long Yubei's figure disappearing into a supermarket. She quickly parked and dialed his number.
"Honey, where are you?"
"No need to wait for me for dinner. Go ahead and eat."
Her brow furrowed. "I asked where you are."
"Where else? Working late at the office."
Gu Lili's heart sank. He was clearly lying.
Was he hiding a woman here?
It was hard not to jump to that conclusion.
"Oh, all right. Then enjoy your overtime—I've gone out for a little stroll too. Talk later."
She hung up before he could respond.
Hmph. Overtime at the office?
She would very much like to see what exactly he was up to behind her back.
Donning a mask and sunglasses, she got out and entered the supermarket after him.
She trailed him discreetly and was astonished to see him shopping for snacks.
He selected a full bag's worth and went to check out.
Gu Lili continued to follow him when he exited, deliberately keeping her distance so as not to be discovered.
Long Yubei, dressed in a light black suit, walked with a calm and unhurried grace. He entered a building through a stairwell entrance.
As soon as the elevator doors closed behind him, Gu Lili bolted up the stairs. If not for her excellent physical fitness, she would never have caught up in time.
Breathless, she reached the eighth floor, leaned against the wall, and cautiously peeked around the corner—just in time to see Long Yubei standing before Unit 801, a bag of snacks in hand.
He didn't ring the bell. Instead, as if it were his own home, he entered the passcode and walked right in.
As the door shut behind him, Gu Lili stood stunned, lips tightly pressed together. But instead of knocking on 801, she rang the bell of 802.
Inside lived a middle-aged couple, unbothered by the news, unaware of who she was.
"Excuse me, may I ask—who lives across from you?"
"A young woman and her one- or two-year-old daughter," the wife replied. "Though we're neighbors, we've never really spoken. I don't know her name."
"And the child's father?"
She shook her head. "Never seen him."
"I see. Sorry to disturb you."
Gu Lili returned to the stairwell, a strange unease gnawing at her heart.
If it were simply a friend or acquaintance, why lie?
A young woman, and a toddler daughter.
No matter how she reasoned it, the fact that he knew the door code suggested a relationship grounded in deep trust—perhaps something far more intimate.
Whether he had lain with another woman before her was something only Long Yubei himself knew.
He claimed she was his first, but he was a man—there was no proof. Who could say for sure?
Once the seed of doubt is planted, it takes root and flourishes with alarming speed.
And if her suspicions were still only speculation, the scene two hours later ignited a smoldering fury within her.
She waited. For two whole hours.
When he finally emerged, it was with a smile on his face—cradling a little girl no older than two in his arms.
A young, beautiful woman followed closely behind, clad in a soft blue dress, her long, slender legs accentuated by high heels.
