For those who haven't seen it. Its about a group of friends, mainly Haruka, Mitsuki, and Takayuki. Mitsuki and Takayuki are best friends, but Mitsuki's best girl friend has a crush on Takayuki. SO... she hooks them up. The anime is mainly about the relationships and a certain life changing event that happens that changes them forever.
Its really good, realistic, soap opera-ish. Only flaw I'd say is everyone thinks the ending isn't very satisfying, but it depends.
