Ok, I'm not disagreeing with you, however, he's not human, so I'm not entirely sure we can equate this with actual DID. If this IS what the author was going for, yeah, that's fucked up.
It was also fucked up that the author went that far, but I don't place any blame on the mc because his actions were innocent. He was consenting to an adult. On top of all of that, it wasn't on purpose in any way, BUT the author didn't have to write it in.
I mean I did laugh initially at the sudden confusion and that the mc came cause it was all super unexpected and such, but after the guy reaction, I immediately felt the same way you said you did.
My only even remotely potential saving grace in this is that they're a god, and that it was an accident. Mc didn't know what's going on and
I was just thinking about this!!!!
I'm REALLY hoping that because they are all the same God/entity, it's just 3 parts of the main entity's personality. Like, the creepy guy being his shadow self, the glasses guy being his truest self, and then the child being his child-like personality. Hopefully it alludes to the third personality just being child like but not a *real* child. they GOTTA clean that up. It's getting weird...
This had potential until that chapter!! Absolutely disgusting they'd establish that one of his sides are a literal child to then switch???? Even making the "old man" protector come would be understandably but that's so sickening no matter what. This writer doesn't understand this type of equivocal real life mental healthcare to do this. That would be traumatic, something a protector would stop for the host. Whoever the host is. Man, wtf? Even if nothing happened after I do not like where this is heading.
