mean girl!chaewon who’s effortlessly intimidating and cute at the same time… short skirts, lip gloss, pretty long brown hair, cold stares and arms crossed, everyone’s lowkey scared of her

mean girl!chaewon who lowkey bullies sweet little nerdy!yunjin at school in that “you’re dumb and ugly and i’d never be into you” way while literally clinging to her arm 24/7 and stealing her glasses just to wear them

nerdy!yunjin who’s known her since forever still lets chaewon drag her around like a handbag, even if she’s rolling her eyes and calling her insufferable

nerdy!yunjin who’s secretly very fucking in love with her best friend but would never act on it (until she does)

mean girl!chaewon who flirts shamelessly in private, straddling yunjin’s thighs while saying “you’re into me, aren’t you? i know you are. you’re always blushing like an idiot” just to make yunjin squirm

nerdy!yunjin who finally snaps one day after too much teasing and just pins chaewon down and says, dead serious, “if you’re gonna keep playing like this, let me make you feel good for real”

mean girl!chaewon who immediately folds. like she acts surprised but melts the second yunjin’s fingers brush up under her skirt

nerdy!yunjin who goes down on her like she’s on a fucking mission. arms wrapped around her thighs, glasses fogged up, groaning into her soaked pussy like she’s praying

mean girl!chaewon who grabs yunjin’s hair and cusses under her breath, biting her lip and gasping between moans like “fuuuuck… you’re such a fucking nerd, why are you so good at this?”

nerdy!yunjin who moans whenever chaewon whines like she lives for it, nuzzling deeper, eyes fluttering shut as she kisses and sucks like it’s the last thing she’ll ever do

mean girl!chaewon who comes from head faster than she ever has in her life, clutching the back of the couch and shaking while yunjin just keeps eating her through the aftershocks

nerdy!yunjin who loves being called good girl, she literally gets hard under her boxers hearing chaewon whisper “good girl… don’t stop, just like that…” while tugging her hair

nerdy!yunjin who’s clumsy with words but insane with her mouth and fingers; overstimulating the shit out of chaewon until she’s sobbing and hiding her face against the pillows

mean girl!chaewon who tries to keep her bratty tone in bed (“is that all you got?” / “hope you’re not done yet…”) but ends up breaking into shaky gasps the second her thighs are spread and yunjin’s stroking slow and deep

nerdy!yunjin who whispers praise the entire time. “you’re doing so good, baby,” / “so sweet for me,” / “i got you— can you give me one more, chaechae?”

mean girl!chaewon who starts fighting subdrop after cumming too many times, and her voice goes shaky and mean like “w–why are you always being so nice to me? i don’t deserve this…” and yunjin immediately wraps her up in kisses, petting her hair with soft murmurs

nerdy!yunjin who always finishes only after her princess is completely satisfied; doesn’t matter how long it takes, she’s down there with stars in her eyes until chaewon’s legs are jelly

mean girl!chaewon who insists on keeping her cold reputation but lets yunjin eat her out in the back of the car, during sleepovers, even in the library— as long as no one else finds out she’s the needier one

nerdy!yunjin who’s secretly reshaped chaewon’s entire idea of control & gives her the illusion she’s in charge, while subtly pulling every string beneath the surface

mean girl!chaewon who eventually becomes a little obsessed, texting yunjin to come over “right now,” getting annoyed when she takes too long, then blushing uncontrollably when yunjin shows up and says, “you called for me?”
