Officer Choi was working in the aquarium and his beloved sister came and showed her the certificate that she won. He came out and he shouted her name and ran to her and hugged her and said that her sister won a grand prize. He also said she did well and she was the best. He was proud of her, baby. Eun-Seol was angry and shouted at him that he always calls her his baby, she asked if she was his daughter or something, which women would marry if he is like this. He said she was her daughter, there are only two of them in the world so of course, you're my daughter. He also said he is going to get her married and then he would think about getting married or not. She said his mind is like that of a grandfather. He asked her what delicious food does she want and he would buy it for her, he also gave options like pork belly, noodles with meat. She was okay with noodles and meat and they both left to have it. He was blabbering that Eun-Seol won the grand prize all his way to the shop. It all flashed his memory once he heard of the name Eun-Seol.
Cho-rim asked him why he didn't leave yet? He glared at her and asked what was her name. She gave me her phone number but she forgot to give me her name. She also said he was very detailed with personal information since he was a cop and her name was Cho-rim. She also asked him to give a sheet to her so that she would write down her name for him. He hands over the sheet with her contact information. She said her name was Cho as in Yangcho and Rim as in Geurim. He asked her but she called you Eun-Seol earlier. She said Song Hyun-Ji mistook me as her friend and then she left. After some time he too left for his house and started to think about her sister's death that he goes to the hospital and calls her name cheerfully and turned her and saw that there were cuts on her neck and lost a lot of blood. He also called the doctor but she was already dead.
He was also thinking that whoever killer my Eun-Seol would kill him with his own hands no matter what. The next morning he rushes to the police station and some talks were going on about which detective dresses like this? or is he going on stage at a nightclub or something? suddenly a reply came that he was going to go tonight. Officer Choi rushed in to see detective Ki and Yen. Detective Ki a sled him who this was? a police officer who caught a robber is here. Detective Yen said that look at him showing off just because he caught a hair salon robber. Detective Ki asked why was he here instead of reporting to the police substation. Officer Choi answered back he was here to see the head of homicide. Detective Ki asked him did he make an appointment but suddenly Detective Yen replied it wasn't funny. Detective Ki banged on his head and said how can it be funny every time? Someone working there said to go inside. After going to his cabin he kicked his leg and certainly told him not to get near a homicide case and if so he was going to break his legs, but he went and arrested a hair salon robber right after what he told too. He asked officer Choi do his words seem funny to him? As if that wasn't bad enough, now he was also asking the head to make him a homicide detective all of a sudden? Officer Choi replies that if he becomes a homicide detective, he would make sure to increase the culprit arrest rate. Head said you must be kidding and asked him do you think you can become a homicide detective randomly by catching a robber? but he says he is confident that he would catch the culprit and begs him to make him a homicide detective. The head agreed and handed over a case file and said he would give him just 10 days, Arrest the culprit and bring and hand it over to him then he said he would be a homicide detective. Officer also said he would arrest no matter what and bring him to you. But the head said if he can't catch him, let's not discuss this ever again.
