Reborn Together with My Wife

On the first day of senior year, a torn couple's notebook lands on his desk, and he understands that Rachel, his childhood sweetheart, has also returned to the past. In their previous life they promised to attend the same college and spend their lives together, but on the night before their wedding she wept that she had wasted ten years on a man she never loved, and then she stabbed him. Now she sits beside Tyler, the new transfer student, while he calmly picks up the torn notebook and gives his place on the math competition team to Emily, the scholarship student from the class next door.

He tells his friend Mike that he and Rachel are simply not right for each other, then stands and invites anyone interested in the math or biology competitions to sign up, declaring that he will lead the team as captain for the next year. Rachel watches him with a strange expression, as though he were the one who wronged her.

While she skips class with Tyler, he throws himself into preparing his team for the national finals, choosing to let them both go.
