Im still creeped out by his cousing showing up out of nowhere like that, and now what he is saying.
What did he know about Seiichi? Or is Seiichi imagining what he is saying? Is his cousin being abused too?? I kinda doubt it but you never know with this manga.
This seems like it's getting out of the realm of psychology and into fantasy. The situation is just too unreal, and doesn't feel like something that could actually happen, unlike all the chapters before this shit.
And then you've become a part of me
You'll always be right here
You've become a part of me
You'll always be my fear
I can't separate myself from what I've done
Giving up a part of me
I've let myself become you
This is how I feel about my dad. Let it all our Seiichi then listen to The Moon Will Sing by Crain Wives and get some anti psychosis meds. You'll be alright.
