Dokt really remember as the girls in the novel have lrgies with other guys too. I can say about this... Romance? no chance, harem? not even mention it. MC gets a girl? Nope
basically one of the girls likes to be gang-banged, the other girl even though she is having s*x with another dude she says she loves the MC then she goes back to have s*x with the other dude along with the other girl resulting in group sex. The MC somehow ends up with engaged with the girl that has quite a few s*x friends but they don't end up together as she goes to search others.... And the MC doesn't want to have s*x with a non-virgin so since every girls he knows has done it already you can guess the rest.
