結婚直前になって彼女がずっと浮気していたことを知った〜絶望して壁に頭を打ち付けたら彼女と付き合う前にタイムリープしたんだが〜

My fiancée—Tooru Kiryu—was cheating on me.

And it wasn’t some borderline case where you could argue about gray areas. No, it was utterly, undeniably over the line.

To be specific, the private investigator I had hired captured a crystal-clear photograph of her walking out of a hotel, arm in arm with another man.

When I confronted her with the photo, Tooru didn’t even try to deny it. Instead, she casually admitted, “So, you found out.”

Worse yet, she didn’t show a shred of remorse—she acted like it was no big deal.

Damn it… how did I end up engaged to someone like this?!

Overwhelmed by despair, I slammed my head against the wall and blacked out.

But when I came to, I wasn’t in a hospital room.

I woke up at a university drinking party—back in the days before I started dating Tooru.

Armed with the truth about her real nature, this time, I’ll escape from the clutches of this wicked woman and seize the happiness I deserve…!
