In this chapter, we're introduced to a new student named Urasebe, who's about to join the class of "new transfer students" at a high school in a big city in central Japan. He's also a "new transfer student" , meaning that he's from a different country than the other students in the class. We're also introduced to his crush, Mikotourabe, who we'll call "Mikoto" because she's his first girlfriend, and "Miyoko" because her first name is "Mi" . Um, what's that all about? Well, it's not really about sex. It's more about the fact that Miyoko is going to be the first girl he'll ever have sex with, and Miyoko will be his first "mystery girlfriend." Um, that's right, Miyoko's name is Miyoko. Miyoko isn't really a mystery. She's just one of the other girls in the school.
