My name is Yoshimasa. I'm an ordinary student. One day my parents moved, forcing me to attend another school. It was a private academy. The school distinguished between three genders: boy, girl and transvestite. I wasn't friendless for long. A classmate named Koyomi talked to me. Then I met the class president Kaoru, and Yuuki, an underclassman from PE. All of us were just discovering our sexuality!
