Doomsday: On a Train, I Make Senior Mai Cry

Su Yang transmigrates into an apocalyptic world and finds himself trapped in the same train carriage as Mai-senpai from the start.

The rules descend, and Su Yang can rewind time endlessly.

Killing zombies can permanently improve his physical abilities, too.

Mai-senpai: "Wah, why are you poking my mouth with your finger?"

Kaguya Shinomiya: "Yang, didn't we agree to just hug?"

Yukino Yukinoshita: "Save me. I don't want to die."

P.S. An apocalyptic train, infinite rewinds, and a harem crossover. Enter at your own risk if that's not your thing.
