Hongjoong is a coffee-hating barista who'd much rather keep his head down and his world small. But all of that starts to change the moment Seonghwa, the charming, ambitious golden boy of their campus, steps up to his counter and orders a drink - igniting a spark neither of them quite knows how to handle.
They barely get along. The first time their hands brush over a to-go cup, it feels more like a challenge than a touch. The last person Hongjoong wants to be close to is the effortlessly perfect Seonghwa...until a messy housing mix-up force them into the most intimate of spaces - roommates in a tiny off-campus apartment.
Suddenly, the two are navigating more than just awkward silence and heated glances. Between midnight conversations, growing affections, a drunken kiss, and a newfound softness beneath their defenses, a dramatic, slow-burning bond starts to form - a bond that neither expected, and neither is sure they're ready for.
As their world tilts and their doubts fade, Hongjoong and Seonghwa find themselves wondering: were they meant to be rivals... or something more?
