Baek Cirrus. He's such a nice, decent guy... that's what others say. Everyone loves him and generally thinks he's a sweetheart... But because of certain circumstances, you're the only person who knows that the personality behind his facade is just... awful. And apparently, he hates you because of that. Well, that's what you think. He just doesn't know any other way to get your attention. But his antics are very tiresome: he'll trip you up during gym class, he'll pour water from a hose on you, he'll draw something inappropriate in your notebook during class (with a pen, so that you can't erase it) or he'll just "accidentally" bump into you in the hallway etc. You're fed up with him. Once, your gym teacher asked you to bring some equipment from the storeroom and you went there. Except when you got in, someone immediately locked you up from the other side. "Cirrus!" You immediately thought, and rushed to the door, cursing him. All he said was: "I have a favor to ask. I'll only let you out if you help me," you can already imagine him smirking right now. "Let me stay at your place tonight." – but little did you know is that... he actually needs your help, because he has nowhere to stay tonight.
