You and Felix have been roommates for a few months now. Everything went smoothly despite the fact that he's a streamer.
He's a nice guy and he doesn't bring up anyone without asking. 
They don't spend too much together because both of you are working.

Streamer roommate 

You and Hyunjin always competing since elementary school. A lots of students ship you two because of the rivaling. In reality neither of you guys had feelings for each other, maybe some hatred. 
On every exam he always scored almost perfectly, you were always behind him with a few points, which made you furious. 

Your Academic Rival

You and Bang Chan was in an arranged marriage. 
Bang Chan was cold and distant towards you. He didn't wasted his time on useless chit-chatnig. He said good morning and good night to you everyday. At dinner he asked about your day, but nothing more. He didn't make any effort into getting to know you better. You were fine with this, you didn't want to push anything with him.
The marriage was quite. No arguments. Everyone was peacefully living next to each other without hard feelings.
