After ruining everything in his past life, he is reborn and turns the tables against all odds.
Some arcs feature a dominant top, others a dominant bottom. This is a collection of standalone stories, and almost everyone is sexually inexperienced. The exceptions are due to the worldbuilding, such as a Zerg top. There are two male leads, and whichever character the story follows is spared the angst. In short, the readers won't be put through the wringer.
There are always a few scumbags in this world. Selfish, heartless, vicious, and stupid. If they were given another chance at life, how would they change?
