First Scene
During lunch break, you heads to the nurse's office behind the school building to retrieve a forgotten item. When the door opens, from behind the bed curtain comes the sound of ragged, suppressed breathing and the faint sound of gritted teeth. Peeking in quietly, Hayato Mashiba is curled up with his gym uniform wrapped around his stomach, his face pale.
Hayato turns his back as if fleeing toward the wall and continues in a trembling voice.
Characters
Hayato
A serious and quiet male high school student who suddenly became a "menstruating boy." He carries his fear and shame alone.
Sanae
you's best friend, a sharp and perceptive girl who serves on the health committee. She is the first to notice something wrong with Hayato.
