Zero to Forever

'Cause Even the Scariest Senior Can Change

Kim Yuna has always known how to survive. Quiet, hardworking, and alone in the world, she juggles school, part-time jobs, and the weight of her past. The one thing she can't escape? Choi Seungcheol-the school's scariest senior, heir to the family that owns their academy, and her relentless bully.

No one knows why he targets her. Not their friends, who share the same performance team. Not Yuna, who hides bruises beneath long sleeves and smiles that never reach her eyes. And not even Seungcheol himself... until the day everything changes.

When Seungcheol leaves for weeks and a new transfer student sets his sights on Yuna, the cruelty escalates beyond what she can endure. One hospital visit, one broken arm, and one unexpected protector later-Seungcheol returns, carrying secrets, guilt, and something even more dangerous: feelings he can no longer deny.
What begins as hatred slowly unravels into fragile truce, quiet gestures, and late-night shadows that feel almost like safety. But Yuna can't forget the pain he caused. And Seungcheol can't forgive himself for being the reason she suffered.

In the middle of rehearsals, café nights, cherry blossoms, and the biggest festival of their high school lives, two enemies find themselves tangled in something they never expected-love.

Can a scarred past blossom into a hopeful future?

Or will the wounds between them remain too deep to heal?
