Y/N has everything figured out, grace, intelligence, wealth, and a carefully curated life with zero room for distractions. She believes in order, boundaries, and emotional self-control. Seonghyeon is the exact opposite. A cocky varsity athlete with a reputation that precedes him, Seonghyeon thrives on attention, popularity, and chaos. He's loud, confident, and infuriatingly sure of himself. He's also Y/N's ex-the mistake she swore she'd never repeat. What they both didn't see coming? They're not just in the same dorm. They're in the same room.

Your ex-situationship is a famous member of CORTIS. He dumped you because he said he wasn't ready for a commitment since their K-pop group was rising in popularity, and you agreed because you're a working student. But one day, while you were on your way home, you saw Seonghyeon outside your apartment.

Martin was never supposed to fall in love with her. It started with a stupid summer bet. Make Y/N fall first. Easy enough for someone like Martin - the charming boy everyone wanted and nobody could keep. But Y/N wasn't like everyone else. She saw through fake smiles, hated players, and made it very clear she wanted nothing to do with him. Which only made Martin try harder. What began as teasing, late-night drives, beach parties, and fake flirting slowly turned into something neither of them expected. Because somewhere between midnight swims and almost-confessions, the bet stopped feeling like a game. And the worst part? Y/N still has no idea it ever started as one. Summer was supposed to end with a win. Instead, Martin might lose the only girl he's ever loved.

The Boy Next Door When cheerful, talkative Y/N gets a new neighbor, she doesn't expect him to be this handsome-or this cold. Kim Juhoon, quiet and mysterious, barely speaks and keeps his distance. But everything changes the night Y/N comes home tipsy and locked out. Unexpectedly, Juhoon lets her stay inside, revealing a softness he tries so hard to hide. What starts as awkward encounters and accidental moments slowly grows into something deeper. But Juhoon carries a secret life as a rising idol-one filled with pressure, rules, and no room for romance. As their connection deepens, Y/N is pulled into a world she never planned to enter, and Juhoon must decide whether to keep his guard up... or let love in. A slow-burn, sweet and chaotic romance about the quiet boy next door, the girl who refuses to give up, and the unexpected love that forms between them.

Y/N has always been "one of the boys." Boyish. Calm. Low-maintenance. The type who prefers oversized hoodies over dresses, guitar strings over lip gloss, and late-night jam sessions over gossip. She's been best friends with Keonho for years - the campus heartthrob with an effortless smile, chaotic energy, and a basketball in one hand at all times. They grew up together. They study Business Management together. They survive college together. They have one unspoken rule. No feelings. No awkwardness. No crossing the line. The bro code. But what happens when Y/N starts noticing the way Keonho laughs just a little softer when he talks to her? Or how he always walks on the outer side of the street? Or how his hand lingers for a second too long when he helps her up from the court? And what happens when Jessica Lee - rich, popular, beautiful, and completely obsessed with Keonho - decides she wants him? Y/N never planned to fall for her best friend. But hearts don't follow rules. And sometimes... You have to break the bro code.
