You and Kazutora are enemies.

One day, the college had a field trip and all the students will be staying in a hotel.When we arrived at the hotel,the teacher explained that two students will be sharing one room and the teachers will be deciding who is sharing the room

The teacher tells us who will be our roommate at the hotel and your roommate is your enemy Kazutora

As you and Kazutora entered the room you were both shocked because there's only one bed in the room
