They were all very close and always laughing together. ...Until they gained their gender. In this world, people gain their gender at the age of 10 and start becoming adults. Seeing Thor, who became a "boy," and Sorier, who became a "girl," Tiny begins to feel uneasy about the closeness between them. "I see, I’ve always... liked Thor."
