Well, that would be The Wallflower. But the guys are rather forgettable to me (though they are entertaining), I watch it for how awesome Sunako is.
Now, they made the guys in The Story of Saiunkoku and Hiiro No Kakera so pretty that I even find them attractive, but I haven't watched to much of the series.
A series where I like all the male characters personalities and find them fun is Miracle Train. Ditto for Ouran Host Club.
A series that I can enjoy for its action and not even think about the guys being "pretty boys" is Brave 10.
