You should have known.
You should have never borrowed money from Mei Mei.
You had a split second of weakness, and now?
Now she was standing in front of you, smiling.
Which was terrifying.
"Y/N~" she purred.
You swallowed. "Mei Mei—"
"Where's my money?"
You winced. "Look, I—"
She tilted her head. "You're not broke, are you?"
You hesitated.
"...Define broke."
Her smile widened.
Oh, you were so screwed.
"Since you're short on cash," Mei Mei said, flipping a gold coin between her fingers, "you can work for me instead."
Your eye twitched.
"Work for you?"
"Of course. As my personal assistant."
You sighed. "What does that even mean?"
She smirked. "Oh, Y/N, it means exactly what it sounds like."
…Shit.
The next day, you found out what "work" meant.
It meant:
Carrying her shopping bags.
Holding her umbrella.
Following her around like a lost puppy.
And the worst part?
She was having the time of her life.
"This isn't fair," you grumbled, arms full of bags.
"Of course it is," she said. "You're lucky I'm so generous."
You shot her a look. "Generous?"
"Yes. I could have charged you interest."
You nearly dropped the bags.
"...There was an interest rate?"
Mei Mei grinned.
"Oh, Y/N, there's always an interest rate."
After hours of "work," you collapsed onto a couch.
"Dead," you muttered. "I'm dead."
Mei Mei sipped her tea, unbothered.
"You're being dramatic," she said.
You shot her a glare. "You made me carry bags for three hours."
She shrugged.
"That's what good assistants do."
You groaned.
Then—
She leaned forward.
And smirked.
"...You know," she said slowly, "if you really want to pay me back quickly…"
Your stomach dropped.
Here it was. The real payment.
"...You could flirt with me."
You froze.
"...Huh?"
Mei Mei rested her chin in her hand, eyes twinkling.
"It'd be cute, wouldn't it?" she mused. "Having you flustered and desperate just to make up for your debt?"
Your face burned.
"That's—" You swallowed. "That's a joke, right?"
She smiled. "Is it?"
Oh. Oh, you were in danger.
"Come on, Y/N," Mei Mei hummed, twirling a loose strand of hair around her finger. "Flirt with me."
You stared.
"I refuse."
She pouted. "That's disappointing. You're supposed to work off your debt, aren't you?"
"This isn't work, it's harassment."
Mei Mei gasped, mock-offended. "Y/N, I'm hurt. Wouldn't you rather have me as your debt collector than some scary old man in a suit?"
You sighed. "At this point? Maybe not."
Her eyes gleamed.
"Then I guess I'll just have to change your mind."
And that's when the flirting started.
At first, it was small things.
Mei Mei leaning too close whenever she spoke.
Mei Mei tilting her head, watching you with amusement whenever you tried to ignore her.
Then she got worse.
She would run a finger down your arm whenever she passed by.
She would call you pet names in the most sickeningly sweet tone.
She would steal your drink, sip it slowly, and then smirk at you.
"Are you nervous?" she asked one day, propping her chin in her hand.
You gulped. "No."
She leaned closer. "Liar."
It got so bad that even Gojo noticed.
"Yo, Y/N, why does Mei Mei keep staring at you like she's about to eat you?"
You groaned. "I don't wanna talk about it."
Gojo grinned. "Ohh, this is hilarious. She's got you wrapped around her finger."
"She does not."
Mei Mei, right behind you: "Oh, but I do~"
You jumped. "MEI MEI, WHAT THE HELL?!"
She laughed. "Why are you so jumpy? Feeling guilty?"
"You terrify me."
She smirked. "Good."
You thought ignoring her would work.
It didn't.
Mei Mei saw it as a challenge.
"Y/N," she purred, stepping into your space, "why are you avoiding me?"
"I'm not."
"Really?" She tapped her chin. "Then why won't you look me in the eye?"
Damn it.
Her fingers trailed up your arm.
"You could just give in," she whispered.
You clenched your jaw. "Never."
Her smile sharpened.
"Suit yourself."
And then, she leaned in—right beside your ear.
"I always win, Y/N."
You felt a shiver down your spine.
Oh, you were so doomed.
"Y/N, Y/N, Y/N…" Mei Mei sang your name, tracing a slow circle on your chest.
You stared at her, feeling completely trapped.
She was sitting on your lap. Again.
"You look like you're about to combust," she whispered, pressing her lips dangerously close to your ear.
You gulped. "You're insane."
She smirked. "And you like it."
"I have a reputation to maintain, Mei Mei."
She tilted her head. "Do you? Because to me… you look like a man who's already lost."
She was playing dirty.
Running her fingers through your hair, letting her lips ghost over your skin, whispering things that had no right being so hot.
And you? You were losing.
Mei Mei leaned back, admiring the way your jaw clenched.
"Are you going to sit there and behave all night?" she mused.
You exhaled sharply. "I hate you."
She grinned. "No, you don't."
You grabbed her wrist.
"You're such a damn tease," you muttered.
Her eyes flashed.
"And you're such a damn coward," she shot back, leaning in, her breath warm against your skin.
Your grip tightened.
"You really wanna test me?" you murmured.
She smirked. "I already won, sweetheart."
The second she called you that, you snapped.
One second, she was teasing.
The next? She was pinned against the wall, her smirk finally faltering.
"Oh?" she mused, intrigued. "Are you finally—"
You shut her up.
By kissing her senseless.
She gasped against your lips, fingers digging into your shoulders, but she wasn't fighting it.
No, she was enjoying it.
"Mm, finally stepping up?" she teased, breathless.
You bit your lip. "You wanted a fight?"
She shivered.
"Make me pay for it then," she whispered.
You didn't need another invitation.
The room was a mess.
The sheets? Ruined.
Mei Mei? Smug as hell.
You, on the other hand? Exhausted.
She stretched, sighing in satisfaction.
"Well," she murmured, trailing a finger along your bare chest. "That was… quite the way to settle a debt."
You groaned. "Never. Again."
She laughed, curling against you, way too pleased with herself.
"You say that now," she purred, "but I know you'll let me win again."
You glared. "I don't lose."
She smirked. "You do with me."
And honestly?
She wasn't wrong.
Silence.
"That should settle my debt," you muttered, throwing an arm over your eyes.
Silence.
Then—a soft, amused hum.
"Oh, sweetheart," Mei Mei purred.
Your stomach dropped.
You slowly lifted your arm, meeting her knowing smirk.
"You think one night was enough to settle what you owe me?" she teased, tilting her head.
Your mouth went dry.
"Mei Mei—"
She slid closer, trapping you.
"You're still in debt," she whispered, fingers tracing your collarbone.
You swallowed hard. "How much?"
She smirked. "At least… another round."
"You're evil," you groaned, hands gripping her waist.
She laughed.
"And you're adorable," she murmured, lips brushing against your jaw.
Your heart hammered.
"You're a menace," you muttered.
She sighed dramatically. "And yet… you're still here."
You exhaled sharply.
"You planned this, didn't you?"
Her smile was wolfish.
"Oh, sweetheart," she whispered, leaning in.
"I always plan everything."
You barely had time to process that before she flipped the script again.
And you?
You were done for.
You didn't stand a chance.
Not with the way she moved, not with the way she whispered your name like it was her favorite thing.
Not with the way she made you feel like you belonged to her.
(You did. You knew it. She knew it.)
After what felt like an eternity, you collapsed onto the bed, completely wrecked.
Mei Mei stretched luxuriously, looking satisfied.
"Now," she murmured, curling against you, "I think we're even."
You let out a weak breath.
"I hate you."
She laughed softly.
"You love me."
You glared at her. "I refuse to answer that."
She smirked.
"Don't worry, sweetheart," she whispered, pressing a kiss to your cheek.
"I already know."
And honestly?
She was right.
