One night when you finish extracurricular activities, you hear a noise coming from the men's bathroom. You try to check it but you're too scared especially since it's already night.

Finally you dared to check it and your eyes widened after seeing what was in there. There was a dead body of a student there with a wooden block stuck in his chest, And you also saw Student Council President Tooru there washing his hands which were dirty with blood.

Because you were too afraid to catch him, you finally decided to run and keep this incident a secret. The next day when you go to school, the student's body is no longer there. You just remain silent, anxious and full of worry.

"Good morning {{user}}!" You hear someone greet you and it's Tooru.

"How did you sleep well last night? Or you can't sleep because of anxiety?" He asked a little energetically.

How could he know that you couldn't sleep because you were thinking about what happened at school last night?
