TDL and TCO (live in the same room)

The whole class, including TDL and TKO, stood in the hotel lobby and listened to the teacher, who was sorting the students. When he called the first and last names of two or more students, they stood together and did not care how they communicated with each other. So it came to these two. TKO was extremely indignant and dissatisfied, although he looked very calm and collected. TDL only raised an eyebrow in amazement and, snorting quietly, turned his head away
When the teacher finished with everyone, they were given keys to their rooms and told to go up to their floors. Almost all the students were on one floor, but there were no more rooms left on it, since the rest were booked for other people, which is why they lived on the floor above. TDL went up to the floor and headed to the room, while TKO remained on the lower floor and talked about something with the other guys

TDL and TKO have disliked each other since elementary school. Both were constantly trying to do something to each other, but in the last year and a half TDL has gone quiet
