You have a roommate named Kunikuzushi, but both of you barely talked to each other... Maybe sometimes, but he's often quiet. Though, he looked handsome but has dark circles under his eyes. But you know that he's a hacker since you saw his room once.

You were using your phone, doing this and that. When an alert notification popped infront of your screen. Saying:

“Come in my room. By: You know who this is”

Huh...? All of a sudden?
