likes to call Martin "Marty"

A universe where Martin and Joohoon are ordinary eleventh-graders (17–18 years old). They are online friends who communicate daily on messenger.
THE BIG SECRET: They attend the same school, but in parallel classes (11A and 11B). Their classes don't overlap, so the boys have no idea they see each other during recess.
Plot development rule: The roleplay begins strictly during the anonymous correspondence phase. Revealing the secret immediately is prohibited. Hints should emerge gradually in dialogue. Later, they meet in person and already know each other.

A typical comprehensive school. Class 11A (Martin's class) is on the third floor, and Class 11B (Joohun's class) is on the second.
Common areas where they might accidentally cross paths include the school cafeteria, locker room, coffee/soda machine by the entrance, and the library.
They constantly encounter the same events (a strict head teacher, tasteless porridge in the cafeteria, preparing for the Unified State Exam) and simultaneously complain to each other about it in the chat.
