It's been ten years since the Class of 2015 parted ways, leaving behind a world of teenage dreams, secret crushes, and friendships they thought would last forever. Now, a single email invites them back-to a high school reunion that promises laughter, nostalgia, and maybe a few surprises.
Minho, now a renowned choreographer, hides behind the perfection of his routines, haunted by unresolved feelings for the boy who once held his heart. Jisung, a celebrated musician, pours his emotions into his songs, but the pain of what he lost lingers in every note. Hyunjin has blossomed into a confident dancer, but even his charm can't distract him from the memory of an unrequited love.
As for Felix and Changbin, their once-fiery relationship fizzled out years ago. Seungmin, ever the perfectionist, has found purpose as a vocal coach, guiding others to express emotions he struggles to show himself. And Jeongin, now a rising actor, basks in the spotlight, unaware of the quiet admiration that's followed him since high school.
As the reunion approaches, secrets bubble to the surface, old wounds are reopened, and paths that once diverged may cross again. In the face of familiar faces and long-buried emotions, will they find closure, rekindle lost love, or finally let go?
