Lee Minho is a cheerful 21-year-old omega known on campus as part of the "Sunshine Group" with his best friends Felix, Seungmin, and Jeongin. While everyone around him is happily in love, Minho is the only one still single-and he never really minded. Until the day he sees Bang Chan. Chan is a world-famous model, a successful 26-year-old alpha visiting Korea for a university campaign with his chaotic best friends, Hyunjin and Jisung. Their worlds are completely different, and Minho knows someone like Chan could never belong in his life. So he tells his heart one simple thing: Don't hope. But sometimes fate has other plans.

For six years, Chan, Minho, Felix, Hyunjin and Changbin have been inseparable best friends. Minho has secretly loved Chan for two years, believing nobody knows. But Chan knows everything. Before it's too late, Chan wants Minho to be his. The problem? Felix has recently developed an innocent crush on Chan without knowing Chan and Minho already love each other. With graduation getting closer, hidden feelings, jealousy and friendships are about to change forever. Will they finally confess before time runs out?
