Wow ! Thank's a lot guys !!

[mizu ashiya]

Definitely second the rec on some of these - Akuma de Sourou, Tennen Pearl Pink, and Nanaco Robin are a few of my faves too.

If you're okay with gender-benders where the girl and boy are roommates, try:
Hana Kimi (http://www.mangafox.com/manga/hana_kimi/) - classic cute story about a girl who goes to an all boys school to follow a high jumping athlete she admires. The two end up as roommates. Innocent and funny.

Power (http://www.mangafox.com/manga/power/) - similar to Hana Kimi, the girl is a little more tomboy-ish and also plays the main sport (basketball) herself.

Tenshi Ja Nai (http://www.mangafox.com/manga/tenshi_ja_nai/) - girl finds out her roommate is not a girl, but a cross-dressing guy who is a famous female idol. Quite spunky and fresh, good art.
