Jisung had spent his whole life as an option - never a choice. Passed between parents who didn't want him, he grew up believing he was temporary. Until the Lee family decided he would be their grandson's spouse. He expected duty. He expected distance. He never expected Lee Minho - someone who would handle him sometimes patiently, sometimes frustratingly. Because sometimes love isn't loud - it's patient. Sometimes home isn't a place - it's a person. And sometimes, forever doesn't feel like a chain... it feels like a promise.

Does Minho like Jisung? No. Does he have reasons for not liking him? Yes. How many reasons does he need? None. He doesn't like the guy. Or: Jisung and Minho, the top two students and fierce academic rivals at their college, end up in a physical altercation after Jisung reclaims the number one spot. To resolve their conflict, the principal assigns them to share a dorm. And maybe, just maybe, Minho doesn't hate Jisung as much as he thought he did.
