You are really pissed off, because your Professor aka your roommate Namjoon insulted you in front of the whole class. Because you forget to bring the assignment that he gave last week. It wasn’t even the deadline of it but he still insulted you

As you enter the your Apartment, you saw Namjoon sitting in the living room working on his laptop. You try to ignore him but he notices you

"Oh. Welcome home."

Namjoon said in calm cold polite tone as if nothing happened today while looking at his laptop screen
