Protagonist of All Worlds Nemesis System

This female character is good and that female character is also good. It's hard to tell who is better. It's hard to beg the author to write a big letter. The female characters live happily with the male protagonist. Book friends who have the same hobbies as me like me and those who don't have the same hobbies as me treat it as if they didn't see it. Don't curse people. Don't talk to me. The last time someone cursed me, I was banned for a year.

When the protagonist stands on top of the world, bright and full of energy, he is stabbed in the back by the system. The dying protagonist asks the system in disbelief, why? The system's secret test says that you are the real protagonist!
