R15+ ja dame desu ka?

How can I grow up and become an adult? Akane Amou has a slight problem with "exciting" things; in fact, she can not watch a kissing scene in a play because her parents forbade her from having any form of entertainment when she was growing up. She is a high school student now, and she wants to get over it somehow! Her intentions are good, but it is not that simple. She also became acquainted with Fuyumine, a movie otaku. Can she see a film that is rated R15?
