Ooooooo Its starting, I read some spoilers on what's to come. Can't wait. Maybe I should wait then binge.

Yes, I mean I'm sorry I made it sound like I had so many spoilers but yes, he starts ignoring him and isolating him from the friend group, which led to him being fully isolated and not protected at all. I think this was him being like I'm going to isolate you so you only need Me (yandere). And when he sees it's not working by that point they already reach college and he tries to go back to how things were but too little too late tbh.

Wow never thought konoha had it in her to defend iana.
Imagine konoha goes yandere for her little sister. I see it. I see it as a better than the alternative of her being with anyone other than Isaac. Also I really want konoha to be like I was only with you to protect iana from you to the crown prince. That would be a twist I can see coming. Also her turning into the demon king herself to protect iana. That would be cool.
....like I get it she loves her dad still but can she please abandon kirigiya household now.
