Everyone likes different things and our taste change over time. What is it about Mikhail that you like?
You hate Aki while he's a main story and Asami's obsession? Pfffttttt
I bet you didn't enjoy the story from the first chapter
Good for you that you managed to love the manga while hating Aki. I haven't read this manga in so long (and I have bad memory) since I'm trying to pile up at least a few chapters before reading again that I don't even remember who Mikhail is but I'm guessing he's one of the distinct characters. And this case with you, yeah, it happens. It has happened to me in other mangas. Though this manga, I'm still at the point of loving this one.
I litterally used to love this manga but it's just too ongoing and the characters have gotten boring... I've always hated aki and I used to love asami... The. Only char that still appeals to me is Mikhail
