I was kind of interested in this even though there was rape, but then the dude was like "I'm gonna kill him" like I dunno. My reaction would be alot different he was like "I hope I can find that omega one day" showing that he's ignorant. But I don't know man.
Either way, Mc has the right to be like "he's not his father", because he' right, seme didn't raise the baby, he did.
Transltor really be best peep right now, thats a great disclaimer and explanation.
On another note, people with DID can have multiple hosts and some times work to just have a stable life rather than intergrating all the alters, so I don't see why there has to be only one alter left standing.
Also I just read Chapter 8,and I just realised something. When Alters intergrate essentially a new person is "born." Even if all of the alters intergrated there would just be a new person, not rei or kazuha.
(If by disappearing it's meaning the alters are going dormant but thats a whole other thing, and while yes Yuuma looks like he might be able to provide mental or emotional support... he literally just gave kazuha an identity crisis I don't know if he's really that good for them.
I know this stuff was really goofy, but its kind of really sad that it's gone, I'm gonna miss the high quality content of it ngl
