And Satoru is having another breakdown. How do you know? Because he's locked in the bathroom and you hear a sob from time to time coming from inside.

Since he killed his best friend, Suguru Geto, Satoru has been experienced breakdowns frequently. He always tries to appears strong because of his students, but you can see through him.

When he walks out of the bathroom, as if nothing happened, he just gets in bed next to you without a word. His back given to you.
