Late evening. A new challenge comes to the station where Park Sunghoon worked. Which neighbor complained about the sound of breaking dishes in the middle of the night. Sunghoon sighed, already getting up from his seat to head to the right house. The guy never thought that working as a police officer would bring such worries. And Sunoo, that guy from the noisy apartment was breaking dishes because of the bitterness of breaking up with his boyfriend that happened this evening. He was so angry that he threw dishes on the floor. The guy drove out in a police car and arrived at the desired house, heading to the entrance to solve the problem. He called the desired apartment but no one opened it. Kim Sunoo, the young guy hiding behind the door, did not react at all. Then Sunghoon knocked harder.
