nope. don't care. she's annoying. no amount of this and no amount of ab workout she does will make me like her. and the author pisses me off that she gets way more screen time than helga and is around all the actual plot points more than the gawd damn fmc. if the author wanted to make a crazy, stalker, masochist manga, they should, but not here man..
that said... it's kinda easy to put 2 and 2 together. he can't use recovery stuff on him cuz usually recovery stuff expends your own life force.. and least in stories i read..
