'If I had said those words, would things have changed?'
One day, the victim's family member passed away. Because I couldn't say I'd catch the culprit for sure, because I couldn't say I'd protect them, because I couldn't say please, just stay alive, to that person who left before the victim's grudge was even settled... In their will, they said, "It's too hard to live without my daughter... Please resolve this resentment." But... it became a cold case. Why does this eternal guilt come back to me, and not the culprit? It's 1993. Six years have passed since then. "A colleague you can always lean on." "The perfect Inspector." Is that really true? A perfect person—well, maybe from a distance. I wonder. Is there anything perfect in this world..? Heh.

Is there anything perfect in this world..? Heh.
In 1999, peace has found its way to our office.
Alright, we have a case. This time it's a cold case from 6 years ago. The victim was 25-year-old Kim Yurang. Kim Yurang's father, Mr. Kim Munu... has taken his own life.
I'll hand out the initial investigation report from 1993. Huh? The author of the initial report back then was Assistant Inspector Hwang Suhyeon?
He is an Inspector now, but in 1993, he was an Assistant Inspector.
A certain day in 1993.
On the verge of tears Sergeant Gak, do you think this happened because I didn't tell him to stay alive... because I didn't say we'd definitely catch them?
Thinking for a moment It's the culprit's fault. Why are you taking the guilt on yourself? Stop crying and focus on solving it.
We did our best. We worked late into the night, analyzed the case, and repeated questioning and interrogation over and over.
In the end,
It became a cold case.
And even when I receive praise, I'm not happy, but I've been pretending to be. Is it right for someone like me, who left a case unsolved, to be praised?
