I'm seeing two sides, tbh... They were never raised as siblings, idk wtf some people here are talking about when all the siblings do in this story is try to sabotage or kill each other, but at the same time, the FL has always portrayed herself as the ML's younger sister, and I see no logic for the ML to regard her romantically.
how?? they litreally raise as family! everyone called her his sister and he as well called her sister and see her that way even if he does not know the truth. he still grow up with her has HIS SISTER!!
and I don't mind if you like it, I don't like to see them has romantic pair, that's why I said if he is the ML I don't want to read this. they feel too much like a bro and sis and grow up together this way.
if Dietrich is the ML then I guess I drop it. I don't ship FL and him at all. they feel more like a bro and sis and grow up together( ̄∇ ̄")
to everyone else, have a nice reading
