Ki Young-han, a prickly college student who's always lived life his own way. Yoon Ye-jun, kind to everyone but quietly strong. Whether by chance or fate, the two are paired together for a group project. From the start, their relationship is rocky—every conversation ends in a clash, and emotional shrapnel flies. All that seems to remain between them is a war-like collaboration. But as they spend time together on the project, small shared moments of daily life begin to draw them in. The once sharp tone softens with subtle warmth, and awkward glances gradually become familiar. Will these two, who once knew nothing of each other, come to recognize the name of this feeling—and take each other's hand?
