Kazuha of LE SSERAFIM never meant to fall for Jake of ENHYPEN. He was her childhood friend-the boy with the easy smile and steady voice who'd known her long before the fame, the lights, and the pressure to be perfect. Reuniting years later under the same company should've been simple, professional even. But Jake's warmth had a way of breaking past her calm composure, and the more she tried to ignore it, the deeper she fell. Then one sleepless night, everything slipped. A single message meant for Sakura landed in the wrong chat. And with it, her carefully guarded secret. Jake-now her senior, her colleague, her crush-knows everything. The teasing texts that follow are lighthearted at first, but soon, beneath the laughter, something begins to shift. Between secret glances, hushed conversations in hallways, and the unrelenting weight of public scrutiny, the line between friendship and something more starts to blur. But idols aren't supposed to love. And when every heartbeat feels like a risk, Kazuha must decide whether to keep hiding behind her practiced smile-or to finally face the one person who's always seen her as she really is.

By day, Huh Yunjin of LE SSERAFIM and Jay of ENHYPEN are elite university students and public rivals-sharp-tongued, fiercely competitive, and always neck-and-neck for the top spot. Their clashes are legendary. Their glares, iconic. To the world, they're sworn enemies with nothing in common but ambition. But behind closed doors? They're married. Forced into a secret union by their powerful families to secure a billion-dollar merger, Yunjin and Jay must juggle campus life, idol schedules, and media scrutiny-all while hiding a truth that could shatter their careers. Living under the same roof with someone you can't stand is hard enough. Falling for them when you're not supposed to? That's war. As rivalries blur into something deeper, and private vows threaten to become public chaos, Yunjin and Jay must decide: Will they keep pretending to hate each other for the sake of everything they've built? Or finally fight for the love no one saw coming?

Scandals in the K-Pop industry are nothing new, but when IVE's Jang Wonyoung and ENHYPEN's Park Sunghoon are caught in a dating rumor, it takes the internet by storm. Fans are ecstatic-two of the most popular idols of their generation, supposedly in love? Their undeniable chemistry on music show stages and viral interactions only fuel the frenzy. But the truth is far from what the public believes. Wonyoung and Sunghoon hate each other. Their history is messy, their childhood ended on a bad note, and ever since then, they've loathed each other's existence. The rumor is a nightmare-but their companies see an opportunity. A fake relationship is the perfect PR move, a way to capitalize on the public's interest. Forced to pretend, Wonyoung and Sunghoon are caught in an endless cycle of staged dates, fake smiles, and insufferable moments together. But as they navigate the act, something shifts. The annoyance lingers, but so does something else-something confusing, something terrifying. Because maybe, just maybe, they never really hated each other in the first place. Maybe they just never knew how to deal with how much they liked each other.
