Even After I Transmigrate, I Still Yearn for Pure Love!

A young man transmigrates to Japan. Bound to a Redemption System, he has no choice but to get involved with all kinds of beautiful girls. As their fates intertwine, they form connections that are hard to let go of.

But what choices can a guy who only wants pure love possibly make? (There is no single heroine...)

Note: The protagonist is a little weird, doesn't follow the rules, and is a pervert (definitely not the typical sweet and gentle Japanese male lead). He's a bit of an overpowered hero, too.

(This is not a fanfic based on an anime or manga. It's an ordinary romantic slice-of-life story, with a little exorcism on the side later on.)
