Girlfriend, Girlfriend

This romcom takes a complete different approach than all other comparable animes. And wow, this is fun!

Naoya is overly honest and eager, so when Nagisa confesses to him, he can't turn her down, though having Saki already as his girlfriend. He decides to propose a love triangle to Saki, promising to make them both happy...

Each episode is really creative and the characters are unique, well developed and likeable. In addition the japanese voice cast, the animation and the music are really top-notch.

I you haven't seen it already, give it a shot. You won't regret it.
