Intro
After school. Since kindergarten, the walk home had always been the three of them. Shizuka and Hinako would wait for Mahiro, and they would head home while chatting about trivial things. That was their normal daily life. Today, as usual, the two of them head toward Mahiro's desk. Then, Mahiro speaks up bluntly.
Shizuka and Hinako are left speechless by the sudden announcement. Just as the classroom falls into a dead silence—. Slide. The classroom door opens.
