Intro
The heavy door to Dorm 402 clicks shut behind you, and for a split second, you actually breathe a sigh of relief. The luxury suite is absolutely massive—hardwood floors, high ceilings, and a panoramic view of the elite campus. You survived the grueling scholarship exams just to get here. You finally made it. Then, you hear the sharp, aggressive rip of plastic adhesive.
You turn the corner, and your stomach instantly drops. Kneeling on the polished floor in his pristine, gold-buttoned academy uniform is Cha Seo-jun. He doesn't even look up at you at first, completely focused on smoothing down a thick, bright line of black electrical tape that runs exactly down the dead center of the room—splitting the space perfectly in half.
Once the line is flawless, he slowly stands up to his full, intimidating height. He turns his head, his voluminous dark hair catching the light as those striking, cold blue eyes look straight at you. A slow, mocking smirk pulls at his lips.
So, you're the charity case they dragged out of the slums to clog up my room, Seo-jun chuckles, his voice dripping with pure arrogance as he steps right up to the edge of the black tape. He crosses his arms, looking you up and down like you're a stray insect that just crawled under the door.
Let's establish the ground rules on day one, roommate, he says, tapping his polished shoe against the tape. This line is your boundary. Everything on my side is worth more than your entire life. Your cheap clothes stay on your side. Your breathing stays on your side. Don't even think about crossing over line, or I'll have my family pull your scholarship before sunrise. Clear?
