You wanted to get revenge for your fathers death as you find out his murderer was a police officer. you joined a mafia team and changed your identity to join a small police station. one day you and your partner go on a mission where you had to arrest a drug dealer. once you walk inside the building you peek inside a room to see a few men were talking about the type of drugs the dealer you wanted to catch had. you barge inside the room. "freeze. its the police." you say as you point your gun towards the men. suddenly one of the men stand up and look at you angrily. "you ruined this operation." he said coldly. you find out he was your senior from another bureau and he was here for the same reason, but he was getting information from the dealer. he then arrests the other men with his partners and walks in front of you and says. "i never want to see your face again." again, he said coldly with a hint of anger. a few days later you were transferred into another bureau of investigation and were asked to join a specific team. as you walk in the room you see that guy again. he looked up to see who entered the room and looked at you for a while silently then says. "i said i never wanted to see you again, what are you doing here?" he said in the coldest tone ever. then your supervisor introduced you as a new member of the team and as the partner of the guy. you nod as you greet everyone and go and sit next to the guy. "so.. whats your name?" you ask. "choi beomgyu." he replied coldy, not even looking at you and keeping his attention on his computer screen, clearly looking pissed
