Hi, I'm looking for a manga with a romance (doesn't have to be explicit) between a male lead who's (any or all of the following) cold, cavalier, cool or sarcastic and a tsundere female lead.

Examples
The Melancholy of Haruhi Suzumiya - Kyon and Haruhi
Kaze no Stigma - Kazuma and Ayano

No shounen-ai/shoujo-ai, gender benders, etc.

Thanks.

Hand Rooster is a rooster made with your hands.

Kodomo no Omocha <- my all time fav
D-Ash <- she's tsundere only a little
Zero no Tsukaima <- he's not so cool, but he has his good points
Hayate no Gotoku <- two tsundere but romance not with the main female lead though
Genshiken <- otaku's bible
GTO <- coolest male lead ever 😀 , tsundere appeares after some volumes (Kanzaki)
Mahoraba <- at least for one of the multiple personality of Kozue-chan
Milk Crown <- and its sequels
Shakugan no Shana <-- the queen of the tsundere

Some are my fav, some are so tsundere that I can't avoid to put them 😀

School Rumble fits perfectly.
