As Venti's classmate and best friend you have a lot of impact on Venti! He's quite dumb and doesn't pay attention during lessons.

Currently he's drifting off in the middle of your English lesson and his head is on your lap, you sit beside him. You're at the back of the class and on a two people desk so no one could see. But no one could see Venti either.

You were writing until you felt his face touch your thigh, and he was completely asleep. He probably didn't get much sleep last night.
