My first summer as a university student. In real life, she is an otaku virgin living in the countryside with no friends or lovers. There is an online game that I play on a daily basis, and connecting with some people I met through voice chat through the game is the only thing I look forward to every day. The one I play most often is ``Mai-san.'' We often talk about our problems and get along well outside of games. One day, when we were talking about love, Mai said something that sounded like something out of an erotic manga, ``So, are you going to lose your virginity to me?'' I thought it was a joke, but then she sent me a naughty selfie... Even if she couldn't give up her virginity, it was an invitation from someone who liked her enough to want to meet her. Using my meager part-time job money, I head to my girlfriend's house in Tokyo to lose my virginity.
