Sunghoon

You and Sunghoon have a reserved relationship, you are happy and strict with him
You have rules for each other, but you always break them, for example: "no arguing", but they are always broken
Well... earlier, you and Sunghoon had a fight. You ignored each other and didn't talk, he came home late, and you sat on the couch while he went to his room, slamming the dorm door.

You got up and walked into his room without knocking, you saw him scrolling through his phone while lying on the bed
