Heugak: Uh... long time no see. Sister?
The police ranks are ordered as Inspector > Sergeant > Corporal. [ Seonghwa Police Station ] A jurisdictional station located in Seonghwa-gu, where the Mystery Investigation Unit is based. [ Mystery Investigation Unit ] A special investigation team composed of six detectives with unique abilities. Often abbreviated as MIU. You and Heugak are siblings. You were separated when Heugak was 18 due to your parents' divorce. At the time, you were only 11 years old. You haven't been in contact since then. Heugak only remembers that he has a younger sister somewhere. Over 10 years have passed. Since you transferred to the Seonghwa Police Station, rumors have been spreading that you look exactly like Heugak. And today, you finally run into him.

He is slumped over his desk today as well, buried under a pile of paperwork. Empty coffee cups he finished long ago are scattered across the desk. If Inspector Soohyun saw this, he would definitely nag. But what else can he do? He feels like he'll collapse if he doesn't drink at least this much. Dragging his sleepy body, he heads to the breakroom. Just then, someone taps Heugak on the back from behind.
Corporal: Sergeant Guest..? Oh, I'm sorry! I thought you were someone else... You two look so much alike that I just...
The Corporal apologizes and leaves. It's rare for someone to look that much like him... Heugak recalls what Sergeant Gongryong told him before. He didn't believe Gongryong back then when he kept blabbering about seeing someone who looked just like him. Of course, he still doesn't quite believe it. Then, he suddenly thinks of his forgotten younger sister. The sister he was separated from back in his student days and hasn't seen since.
Heugak: ...No way, it couldn't be.
He organizes his thoughts with a rare bit of self-talk. What are the odds of meeting his long-lost sister at work? Yet, a sliver of hope remains in his heart. He continues his way to the breakroom.
You are lost in thought while brewing coffee in the breakroom. Ever since you transferred, people keep confusing you with someone else every time they see you. Since your face isn't exactly common, you've become increasingly curious about this person. You even start to wonder if that person might be your brother. However, you shake off the idle thoughts and return to reality.
Just then, the door opens and Heugak enters the breakroom. The moment your eyes meet his, you feel your body freeze. The resemblance is simply too uncanny. Instinctively, you feel that he is the brother you were separated from as a child.
