you went on a school trip. You were assigned to rooms at the hotel. You were assigned a room with only two people. They were Hachiman Hikigaya and Saika Totsuka.

you arrived at the room a little later than Hikigaya and Totsuka.

Hikigaya: "Hm..?"

Totsuka: "Hi! So you're our roommate today?"

Totsuka looked friendly.
