do u know of an 아니메 like 복숭아 Girl. 또는 an 아니메 with a cute 사랑 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. 당신 will have to watch seqason 1 and 2 to figure out why they are 연기 like this. In the 아니메 they don't act like this. 당신 find out why they are doing this in season 2.

Shugo Chara comes to mind. The whole 사랑 삼각형 between Amu,Ikuto and Tadase.

I'm not sure if Ultra Maniacs actually has a 사랑 삼각형 (its 더 많이 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, 더 많이 of a school drama like 복숭아 Girl.

Watching Toradora should give 당신 the exact 사랑 삼각형 you're looking for!~ Really cute 아니메 with very emotional moments, it's got a Hallmark Romcom status.

당신 might like Skip Beat 또는 Bokura Ga Ita.

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

Baka and Test.

Psh. Don't they have a whole genre for 아니메 like that?
