Sakura Diaries

Sakura Diaries failed to be anywhere near as ecchi as they made it out to be. So if you don't worry about the ecchi or the idea of kissin' cousins, Sakura Diaries is a nice little romance. I particularly liked the idea of Mieko (the object of Tonma's affection) being manipulative and stringing Tonma along.
The series didn't have one of those definite conclusions, but it ended very nicely - and with a character montage of all things! Also the characters had consciences - so after they commited acts of bastardry they felt remorse. I liked that.
