With Infinite Save Slots, I Don't Have to Fear Death

Le Yiming is an ordinary high school senior. During a shooting, he awakens the ability to save infinitely in a loop in order to rescue the girl of his dreams.

Afterward, Le Yiming receives an admission letter from Dumlanz College. On a stormy night, he and his senior head to the airport. A huge black figure lurks in the rain beyond an elevated bridge and attacks them, kicking off a thrilling and perilous night-time assault.

This is not a commercial harem novel or a formulaic story. It's a breath of fresh air in the industry (or so I say). If you want to give it a try, I recommend starting at Chapter 28.
