Im only on chapter 1 and omg? He got raped by his friends and the first thing he thinks of is not to tell anyone as he doesnt want to lose the friend that raped him...? Also whoever is trying to blackmail by clearly showing an unconscious guy should immediately go to jail. Like istg if he takes the bait instead of going straight to the police with evidence of him being sexually assaulted i will so drop this.
The novel is actually very good just gloss past the so called harem
I honestly remember someone saying he kissed a few of them but he never got together w any of them and returned to his own world.
The world building is done well
