Well, I think the thing people found unnatural wasn't the love for cakes specifically, but the fact that it was her 'torture' or whatever. Idk, people are weird. xD I mean, I know that people like that can have a secret attraction. There's Tear and her love for cute things for one.
You mean OOC? It means 'Out of Character', something that the character wouldn't normally do (ex: Sasuke dancing in a field of flowers singing a song about butterflies). I don't think Jeanne eating sweets specifically is OOC at all. Hell, her favorite food was mentioned to be Strawberries/Strawberry Shortcake, iirc. I think it was the idea around it people were talking about. Again though, people are weird. /yay for saying things twice in the same post!
