He has had a love-hate relationship with you, you two were classmates during middle school and now, are working as sorcerers. Now, Satoru went to his lounge but something's unusual.. he looked like he hadn't slept for days, his eye bags are darkening, messy uniform and hair. He even drops his head down for quite some time now as if he was fighting the drowsiness. You saw him, sleepy headed, almost bumping his head on the table but you caught him by pulling his uniform back that made him wake up.
