Please help! I'm trying to find the name of a shoujo manga. It's about a girl whose father dies and leaves her a note telling her that there's a guy who will look after her. She finds the guy and he's a high school student living in a boarding house (with a bunch of weird characters including a fake gangster and a crossdresser as the head of the dorm) who says that she's his fiance.

Is it Harem Lodge?

That's it! Thank you so much!
