I'm looking for a shoujo manga/anime with a tsundere male lead but really loves the girl. The male also falls first. He is rude towards everyone else but a little nicer to the female lead(just a little). He can also be a bit clingy and cute when he is jealous. The female talks back to him and they always argue a lot but they're love is shown when a situation calls for it. I dont mind if it is a child romance(like elem or middle school)they are cute too but it should not be harem. Is there a manga/anime like this?

Kodocha (one of my personal favorite series)
Gakuen Alice
Takane to Hana

Not tsundere guy, but these have the love-hate thing going on:
Special A
Kaichou wa Maid-sama! (tsun girl instead)
Lovely Complex

There's a lot more, but it might bet better to use the advance search via tags. Such as tsundere + male lead falls in love first

I'm in idol hell T.T

Ive watch kodocha and Gakuen alice, its my favorite too. I'll check out takane to hana. Special A and maid sama are awesome too. Ive heard of lovely complex before. Thanks a lot.
