Some scars are not meant to fade. But we are not our scars.

Can you forgive yourself for a tragedy you didn't cause, but couldn't stop?

One year after his identical twin dies by suicide, Noeul is barely surviving. Consumed by guilt and convinced he deserves to suffer, he withdraws from the people who love him, carrying the weight of a past he cannot change. Every day becomes another act of self-punishment, every memory another reminder of the life he believes he failed to save.

But the past refuses to stay buried.

As Noeul becomes entangled with Chung-Hee, the older brother of another victim whose life was shattered by the same tragedy, grief and resentment blur into an unexpected connection that neither of them knows how to escape. At the same time, Duri, a loyal friend who has quietly loved Noeul for years, refuses to give up on the man everyone else believes is beyond saving.

Caught between guilt and forgiveness, first love and unconditional love, justice and compassion, Noeul must confront the question that has haunted him from the very beginning:

Can someone who cannot forgive themselves ever allow another person to love them?
