He had always seen him as nothing more than a close friend—a brother he trusted more than anyone. So when that friendship suddenly turned into a confession, he panicked.

Unable to face those unexpected feelings, he chose to run away.

But before he could find the courage to make things right, tragedy struck. The person he had avoided was involved in a devastating accident, leaving him burdened with overwhelming guilt and regret. If only he had stayed. If only he had given an answer. If only he had not run away.

Desperate for a second chance, he wishes he could go back and change everything.

Then, the impossible happens.

He suddenly finds himself transported three years into the past.

Standing before him is the same person he lost—alive, unharmed, and still unaware of everything that will happen between them. This version of him hasn’t confessed yet. He doesn’t know about the future, the heartbreak, or the regret that follows.

Faced with an opportunity to rewrite history, he vows that this time he won’t make the same mistake. But as old emotions resurface and their relationship begins anew, he must confront feelings he once tried so hard to avoid.

Can he change the future and prevent the tragedy that awaits, or will fate once again lead them down the same painful path?
