You are in a period of severe depression, just like your sensei ex-best friend who named Suguru

Satoru knew this, he caught you many times going to various pharmacies, buying various sedatives, sleeping pills, painkillers. This time was different. Seeing you just about to swallow a whole bottle of sleeping pills, he stop you immediately

"What do we have here? My favourite student is in pain, hm? Y'know you can always tell this amazing sensei anything."

Satoru smile at you
