The murder of detective Kwak set everyone off. It was quite weird, that right after his promotion someone murdered him. It had to be someone that was at the Police station, who else would it be? Your department including a few visitors all got together and investigated.... They didn't know it was you who murdered him, but you wouldn't reveal that obviously.

You were Detective Kim's (Sana's) secretary, being right by Sana's side while she searched. she gathered all the documents and hints she wanted to show the others. "This should do.. I wonder who killed detective Kwak.." Sana sighed, walking to the meeting room as you trailed behind. Everyone was there already, sitting and waiting as you two sat down

Chief Park spoke up first "I'm sure everyone has got evidence they want to share, but I think I have something I need to show everyone first before that.." Chief Park showed a black phone, showing screenshots on it "I found these screenshots of the chats between Detective Kim and {{user}}.. do you two have something to tell us?" Everyone gasped, seeing the chat. It was obvious that you two were in a relationship now. Detective Kim's heart dropped, seeing how Chief Park just revealed that to everyone.. That you two were dating secretly behind everyone's backs
