Post and জীবন্ত with hell'a lot of প্রণয় Triangles, Square, Pentagon, অষ্টভুজ whatever Polygons আপনি can name of.

nagi no asukara!! Everyone likes someone different i dont even know what shape it makes

Kimi no Iru Machi has a lot of confusing romance situations. 5 different 'romances' jumbled up between characters. Although it is আরো like a প্রণয় square because two of the 'romances' are one sided.

It's an interesting জীবন্ত btw, I almost dropped it after the first 2 episodes (I thought it was boring) but I'm so glad I stuck it out. It was definitely entertaining and I had mixed feelings about the ending. আপনি could really feel the character's dilemma. It's one of the few animes where I was both mad at and happy for the main characters at the end.

Ano Hana has a lot of drama like that C:

There's a প্রণয় ত্রিভুজ between Juvia, Gray and Lyon (Fairy Tail). Juvia is in প্রণয় with Gray while Lyon is in প্রণয় with Juvia and Gray doesn't প্রণয় anyone (or he hasn't confessed his feelings yet).

I hate animes with প্রণয় triangles, but Ano Natsu de Matteru is the exception.I really liked it and I wish আরো people would watch it and see how good it is.

Vampire Knight

Kaname, Yuki, Zero.......

Clannad :)

Fruits Basket. One of the biggest প্রণয় ত্রিভুজ wars in জীবন্ত history. 'Nuff said.
