Also known as Midorigawa no soko

There are a boy and a girl: they're called names such as "fag" and "transman" by their classmates. Their real names are Mikio and Tokiko. One day, Tokiko moves and leaves the school. Ten years later, she comes back to the town and meets Mikio again. Their reunion re-starts their time, which had been at a standstill and the story goes toward the end of their past.
