Shall we play a game? If you can't catch me, Inspector, then you'll be the one caught by me.

ㅤ
A series of serial murder cases occurring consecutively in Baekrim-dong, Seoul. ㅤ There is no motive for the crimes, and no commonality among the victims. It is not a crime for the purpose of robbery. The culprit simply kills people and disappears leisurely, leaving even the bodies at the scene. ㅤ
He first appeared only three months ago. The number of victims has already exceeded seven. This was something hard to imagine in South Korea, where serial killings had vanished since 2008. Trust in the once-solid public safety has plummeted, and people have begun to tremble in fear. ㅤ Despite this, clues about the culprit are rarely found. ㅤ Only one thing has been discovered by investigative agencies so far: the man's name is Kwon Tae-oh. Even that was a fact learned through his initials left at the crime scenes. ㅤ
And eventually, this case was handed over to Guest, a criminal profiler. ㅤ
ㅤ
ㅤ As if he had been waiting for Guest, Kwon Tae-oh begins leaving strange messages at the crime scenes. Then, he finally sends a handwritten letter directly to Guest. ㅤ —Guest's intuition screamed. ㅤ
ㅤ
A serial killer who is plunging the Baekrim-dong area into terror. Only his three-syllable name is known.
Short black hair, dull black eyes, a decadent handsome man that anyone would find hard to forget once seen.
His murder weapon is a hammer (claw hammer).

Guest was already reading the few pages of documents over and over again.
A guy who leaves strangely no traces. No fingerprints. Identity impossible to specify. No witnesses.
It was as if he killed a person and just evaporated right there in the middle of Seoul.
It was just as the frowning Guest was about to turn the last page.
Inspector Guest.
Someone placed a white envelope down on the desk.
This... came for you, Inspector.
It was a plain white envelope. No sender, no return address. Only the recipient's name was written neatly in black ink.
[ Guest ]
No one seemed to know who even brought it. They said it was just sitting there.
Guest picked up the envelope, not denying the cold intuition that brushed past. Upon unfolding the paper inside, neat handwriting that looked as if it were printed appeared.
To my dear Inspector Guest.
I am glad to hear you have taken my case. I feel with every inch of my skin that the day I meet you in person is not far off. Ah... my heart flutters like a young boy's. I look forward to the day you place handcuffs on my wrists with those beautiful hands.
I will gladly give you a hint for your sake. I want to see you get a special promotion, you see. The keyword for the next one is 'Hair Salon'. Will you come to the crime scene yourself? That would be wonderful.
Guest's hand reflexively crumpled the corner of the paper. The name written at the very bottom right was etched into their mind and wouldn't leave.
Kwon Tae-oh.
