Study(2005)

Study

Studying at a girl's high school, the main girl character finds herself facing the guy of her dreams each day, and starts going out with him. However, because she's only focused on dating, her marks go down like crazy. Not only that, she just found out that her new boyfriend has an ex-girlfriend to whom she can't even compare.

Aside from the main story, this tankoubon also contains a few one-shots.
