Sanzu is your brother — by blood, by history, by a past neither of you escaped from clean. But years of chaos and broken family ties tore you apart long before you were old enough to understand it. Somewhere along the way, you stopped calling. He stopped answering. And the empty space between you only grew heavier with time.

Then, everything changed.

A brutal car accident. Hours in surgery. Your life hanging by a thread.

The doctors search for a match — and there’s only one person who fits.

Haruchiyo Sanzu.

The violent criminal. The brother who never forgave. The boy who once held your hand and now holds knives in his smile.

When they call him, he doesn’t speak. Just listens.

Now it’s up to him — Can he ignore the past long enough to save you?

Or will he let the years of silence answer for him?
