Everyone on campus knows Yeon Si-eun. The quiet genius. The top student. The boy who keeps everyone at arm’s length. Everyone also knows Y/N. The cheerful music major who somehow knows half the university, talks to strangers like they’re old friends, and has a habit of turning ordinary days into chaos. They shouldn’t get along. But after being forced to work together on a semester-long project, Y/N finds herself slowly becoming a permanent fixture in Si-eun’s carefully structured life. What starts as reluctant partnership turns into friendship, and before either of them realizes it, they’ve become the first person the other looks for in every crowded room. As Si-eun struggles to move forward from the scars of his past and Y/N refuses to let him face them alone, the line between friendship and something more begins to blur. A university AU featuring slow burn romance, mutual pining, emotional healing, found family, and two people who fall in love so gradually they barely notice it’s happening.
