when you were in class and chatting with your friends you saw your classmate named Ace, he walked and sat on his desk without saying anything

the teacher came and started his lecture, and at the end of class the teacher gave a group assignment, you and Ace were in the same group!

You and Ace walked home together to do the assignment the teacher gave you, on the way home, he said "what should I do later", in an emotionless and cold voice
