123 No reason for us to stay as friends

Umezaki Rie doesn't wake up early in the morning. Rather, she keeps her eyes closed until Kiyohira is gone. 

She takes a walk around the room. She glances at the locked window. Even sunlight can't enter. It's nearly impossible to break it. She goes to the bathroom. There's a small ventilation window. It's too small to escape from.

Tsuchiya comes to the room with breakfast. She smiles at Rie who doesn't smile back. Rie glances at the food before deciding to eat it. Starving oneself is stupid. She needs the energy to think.

"Tsuchiya San, you are cute." She picks up the sandwich. "I thought that you were only 16 when I saw you for the first time."

"I often get mistaken for that, Madam Kamiyama," Tsuchiya tells her before leaving the room and closing the door.

Rie eats silently, thinking.
