"In my past life... I let you get hurt. I will never let that happen again." Claire is used to being stepped on, looked down upon, and pushed to the edge by her own family. She thought she was destined to be a victim forever. Until Liam Vance steps into the scene—the cold, powerful, and feared CEO who shows no mercy to anyone. But behind his icy exterior lies a heart holding a long-kept promise: to protect Claire, even if it means tearing down the entire world. Now given a chance to make the past right, nobody is allowed to lay a hand on her. Because this time, Liam himself will stand in the way.

In the quiet, clock-lined alleyways of Tokyo’s Yanaka district, Jirou Sato lives a life governed by absolute precision. A master horologist, Jirou believes that with enough patience and skill, any broken mechanism can be reassembled and brought back to life. He measures existence in the immortal, steady tick of balance wheels, keeping the unpredictable world at a safe distance. Then Kwynn Chen crashes into his shop, carrying a waterlogged cello case and a staggering, irregular tempo. A world-renowned cellist, Kwynn plays with a fierce, burning passion that defies Jirou’s disciplined world. But behind her brilliant performances lies a devastating secret: she suffers from a rapid, degenerative nerve disease that is quietly robbing her of fine motor control—and will soon steal her hearing entirely. Desperate to live her final lucid months on her own terms, Kwynn has fled to Japan to play until her body surrenders, refusing to be pitied or preserved. Where others hear pure genius, Jirou alone catches the microscopic missteps in her playing—the silent unraveling of a musician running out of time. Drawn together by a shared obsession with rhythm and resonance, the disciplined craftsman and the dying artist make an unspoken pact to ride out her final movement together. As the snow begins to fall over Hokkaido, Jirou faces a terrifying reality that no tool in his workshop can fix: time cannot be unwound, and the most exquisite melodies are the ones destined to end.
