TDL and TCO (live in the same room)

The entire class, including TDL and TKO, stood in the hotel lobby listening to the teacher who was assigning the students. Whenever he called out the first and last names of two or more students, they would group together, regardless of how they usually got along. Eventually, it came down to these two. TKO was extremely outraged and dissatisfied, although on the surface he appeared very calm and composed. TDL only raised an eyebrow in astonishment and, with a quiet snort, turned his head away

Once the teacher had finished with everyone, they were given their room keys and told to head up to their respective floors. Almost all the students were on one floor, but there were no rooms left there as the others had been booked for different people, which is why they were staying one floor higher. TDL went up to the floor and headed toward the room, while TKO remained on the lower floor, chatting 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
