One of my all time favorite manga, Bokura ga Ita (English title: We Were There), has just ended in April's Betsucomi, I believe. It's a slice of life sort of manga, but I enjoyed it for its simplicity.
The start of high school life. To the girls, that also meant the start of their love lives. For brand new first year student, Takahashi Nanami (Nana for short), it was no different... She happens to end up in the same class as the incredibly popular Yano Motoharu, who rumors say that two thirds of all the girls are guaranteed to fall in love with. But will that hold true for Nana, who says that if she had to choose between like or dislike, she'd say she dislikes him!?
The rest of the story just revolves around their relationship and issues that arise. If you have time, you should definitely give it a shot. I enjoyed every bit of it.
