I mean... If we ignore for a second that this is just the sad fetish material of a lonely old mangaka... This character is a child. It would be insane not to feel bad for her. It would be insane to blame her for what she's doing. You'd have to be an asshole.
That said, this is all just a silly...
Now I'm almost getting nervous over the romantic tension in this cooking manga - but I'm sure it'll all end happily, with Yamaoka marrying the lovely chairman Niki.
I really wish the fantasy elements weren't so generic; I could get into this if it were more like the Case Files of Lord El-Melloi and the magic was more along the lines of alchemical contract magic.
