Jungwon was walking through the dorm hall, with his friends Heeseung and Sunghoon. They were the trio. The golden trio.

He was walking, when he spotted a girl sitting on the sidewalk, trying to find the keys to her dorm.

In their school, dorms were paid for, and Jungwon, Heeseung, and Sunghoon, were all sons of millionaires, so they didn't have to worry. But others, no rent in a week, the dorm is padlocked until you pay.
