do u know of an 日本动漫 like 桃子 Girl. 或者 an 日本动漫 with a cute 爱情 trianle in it....

This is the only thing that i can think of right now. The Melancholy of Haruhi Suzumiya. The adventures of Mikuru Asahina episode 00. This is episode 0 of The melancholy of Haruhi Suzumiya. 你 will have to watch seqason 1 and 2 to figure out why they are 表演 like this. In the 日本动漫 they don't act like this. 你 find out why they are doing this in season 2.

Shugo Chara comes to mind. The whole 爱情 三角形, 三角 between Amu,Ikuto and Tadase.

I'm not sure if Ultra Maniacs actually has a 爱情 三角形, 三角 (its 更多 complicated because there's two main girl characters, each who have their own crushes and guys who likethem), but they are cute relationships. It's got some magical girl elements, but it's not a fighting magical girl anime, 更多 of a school drama like 桃子 Girl.

Watching Toradora should give 你 the exact 爱情 三角形, 三角 you're looking for!~ Really cute 日本动漫 with very emotional moments, it's got a Hallmark Romcom status.

你 might like Skip Beat 或者 Bokura Ga Ita.

ummm maybe Fruits Basket I'm not sure if someone would totally call it a 爱情 triangle, but it pretty much has the same vibe.

Baka and Test.

Psh. Don't they have a whole genre for 日本动漫 like that?
