Kaichou wa Maid-sama!

In both mangas, the main female is a tough girl, and
they aren't very good with relationship problems.
Another similarity is that in both mangas, the main male character is one of the best looking guys in school, and they both have girls over all them, though I think I like the male lead in kaichou wa maid-sama a bit more.
