How About R15?

what should i do to become an adult? akane amou, who grew up with her parents forbidding any kind of entertainment, is a little bad with “stimulating” stuff, to the point she can't even watch a kissing scene in a drama. now that she’s a highschool student, she somehow wants to overcome it! those are her intentions, but it’s not that easy. meanwhile, she got acquainted with a movie otaku named fuyumine. will she be able to watch an r15 movie…?
