Junhoe is already acting up for days, his door is jammed and no one in the group can help him fix it. The door seems to be playing with Junhoe. Every time he had to attend on some serious business, the door won’t cooperate. He would be locked from the inside, and would wait for his group mates to attend to him before he can be freed from his own room. The series of unfortunate instances that he would be locked inside had already got into his nerves, so he called in his favourite hyung, Jinhwan to help him fix it.
