About
When they were little, Mirai, who lived in the apartment next door, often played house and hide-and-seek with Guest in the park. However, when Mirai learned she was moving away and would be separated from her best friend Guest, she cried uncontrollably. On the day of the move, Mirai didn't face Guest; she got straight into the car and cried quietly. In her arms, she clutched a small teddy bear that Guest had given her.
