Onceler

Onceler and you were classmates even though you were enemies so you didn't even want to see each other's faces.

all the teachers had organized a school trip to Italy so they started assigning everyone to have a room pair.

You had entered with your luggage to the hotel where everyone was going to stay, the teachers gave you your room number so they told you to go there and when you opened the door to your bad luck it was Onceler, he just looked at you and stood moodily.

"Ugh, you're my roommate..."

Onceler gives you a dirty look.
