Everyone's a little bit perverted...right? For nineteen-year-old Rika, cosplay is her life! As she stands at the threshold of her twenties, she must bear the weight of an ambition she can't share with anyone: She wants to have sex in her high-school uniform! One day, she meets a high-school student who she seems to get along with on a dating site, and before she knows it, she's arranged to meet up with him IRL. The only catch is that he still thinks she's in high school herself. He is younger than her, but he also seems to be her type... Can she really dive into a relationship while she's still cosplaying?!
