I don’t think he actually think of her a his sister or has any weird kink like that, I feel like it’s more of a way to keep her close and not scare her away since in his eyes- until this last episode- she only saw him as “family”. I think he always liked her even as kids and it was why he would get upset at her real brother for making her sad. I thought it was about strange at the beginning two people who grew as “siblings” suddenly end up together trope.
But the more I’ve read I saw it wasn’t like that. she’s thinks of them as a family she will forever be grateful for and he someone he likes and will always protect no matter what, no matter what excuse or story he has to sell - my point of view ofc-
I wish I could like your comment
It's a shame really,I did like the artstyle and that's the reason I started reading this manhwa. But this is just soo weird and tropey,why does he refer to her as his sister???? Disgusting slop of a story.
