After investigating the book and seeing the similarities and looking at the twisted, vile nature of this author's other works I think it is very likely they were inspired by Nabokov's Lolita for this particular manhwa. Perhaps Ramjak is intentionally making Lumi look more and more like a child as the story goes on to illustrate that she is a child that is being sexually abused and manipulated by her stepfather. Doesn’t make the story and sex scenes any less gross but just something I thought of.
I really want to see more of lord Wolflake too, he seems interesting. Kloff needs to grovel and go through extreme pain. Aeroc in the original timeline did something terrible but nothing that warranted such psychological and physical abuse. Especially because I feel like a lot of Kloff’s rage and violence is internalized homophobia due to what we are seeing with the new timeline. Or I guess it would be called alphaphobia? Aeroc‘s poor beautiful six children.
