He left once-and if you're foolish enough to believe you can make him stay this time, then by all means, try.

Lee Erin lives by one rule: don't fall in love. It's foolproof-until Nishimura Riki, her brother's insufferably charming best friend, makes it his mission to turn her quiet life into his personal comedy show. Stealing her snacks? Check. Teasing her at school? Daily. Smirking at her murder glares? Absolutely. For Ni-ki, annoying Erin is a sport, and her frustration is his trophy. When her meddling mom tries to set her up with the "perfect" but brooding son of a family friend, Erin makes a desperate move-fake-dating Ni-ki. He agrees, but of course, he doesn't make it easy. Between staged hand-holding and not-so-fake flirting, Erin finds herself laughing more than glaring. And Ni-ki? He might just be falling for the girl who swore she'd never fall for anyone. It started as a fake relationship, but is their love-hate dynamic turning into something dangerously real? Or will Erin stick to her rule and break both their hearts?

y/n, a cheerful and funny girl (sunshine), and jungwon, the grumpy, direct bad boy, share a close friendship that seems unshakable. but as their bond grows deeper, feelings start to develop that neither of them is prepared for. they both try to ignore what's happening between them, but it's getting harder to deny. will they let their emotions take over, or will they fight to keep their friendship intact? as their connection intensifies, they'll have to decide what it really means to be close to someone... tw // emotional conflict, anxiety, self-doubt, fear of rejection, unspoken feelings, unintentional hurt, smut

she was the girl ni-ki was never supposed to care about. loud arguments, sharp comebacks, and constant tension - they were enemies, everyone knew that. So when a stupid bet with his best friend dares him to prove he feels nothing for her, ni-ki agrees without a second thought. easy, right? but the more time he spends trying to "prove" it... the harder it gets to lie - to her, to sunghoon, and especially to himself. because the only thing worse than falling for her? falling for her while she still thinks you hate her. tw // rumors. harassment. slutshaming. emotional conflict. heavy angst. strong language. nsfw scenes. messy friendships. complicated love. read with care - not everything is soft here
