I Don't Want to Die, So I'm Going to Raise a Hero

A university student named Osaka Nao reincarnates as the villainous young master Lian in a game.

“Hey, is it okay if I touch you more?” The unrefined hero's unconscious pampering makes Lian's heart race—unavoidable heart-throbbing moments. (Source: justforbookmarking @ Batoto, modified)
