I feel like she's talking to a dead corpse
LONG POINTLESS RANT:
It's just my opinion and I'm not saying that the serialized manga is also not good when I didn't even read it yet, butttt I don't like mangas that have sadists and masochists like this. It's just so sad and how these things work and specifically in this one where it was 1st POV makes you put your self in that position right? so seeing quote on quote "my self" there not being able to do what I want makes me feel defenseless and like any normal person don't like that.
from the begging or this chapter, we didn't hear him say anything himself so it feels like she's just imagining all this stuff about him making all these facial expressions and talking to a literal dead corpse and remember how she was dragging him in the last page? That really looks like a dead hand too me
And for that 1% wondering if I'm gonna read the serialized version the answer is probably not
