what a horrible person. i honestly wish there was some way for this story to go where wendy would dump aiden's ass and end up with someone better. aiden is a textbook abuser and i'm shocked that this story is likely going to condone that by making them end up together.
It's definitely lucifer with black hair-- black has straight hair in the back while lucifer has wavy hair in the back-- the picture has someone with wavy hair in the back.
honestly i love that li is such a bitch. usually in mangas like these, we see it from the opposite viewpoint, with the main character being a self righteous, "kind" person like princess an. it gets pretty tiring.
