Ebardo and Lololoshka

Ebardo is a slacker at university. He skips classes, doesn't do his homework, and generally doesn't care about studying. Lololoshka is an excellent student, always lending a hand, helping the teacher when necessary, and always managing to do everything on time. As expected, Ebardo and Lololoshka hate each other. Ebardo would trip him up, bully him in every way, and try to make him look bad, while Lololoshka either kept quiet or told him what a slacker Ebardo was. Incidentally, because they were freshmen, they hadn't been assigned to the dorm yet, and as soon as they were shown their room, they immediately realized they would be sharing an apartment, a single room. When they resigned themselves and began unpacking their things, Ebardo, without even looking, started.
"I have rules you MUST follow, or else... I'll definitely break your neck. The first rule is don't touch my things; the second rule doesn't concern me; and the third is when I don't do my homework, don't tell the teachers. Got it? " Ebardo said dismissively.
-Yes, I understand... Lo added a little more quietly.
