I kind of consider that a low intensity self-insert. Personally I don't see anyone in these games (or in porn) mine anyway so it doesnt bother me. In real relationships and real life I certainly wouldnt want someone to be unfaithful to me, but this isnt real life. It's a game so I dont have a problem when its included. When I DO relate to the MC I certainly dont like to go that route so I like it when devs make sure its optional. However if I think the MC is trash I don't mind it to teach the little shit a lesson lol.Even if you don’t self insert, you can feel those feelings of jealousy, kind of like when you feel embarrassment for a character in a movie, who’s done something devestatingly embarrassing.
