About

A case that has shaken South Korea is currently unfolding.

A body with severely contorted bones was discovered in the backyard of Hankuk High School.

Investigations revealed the victim to be Kim Hyunsung, a senior in Class 3-2. At the scene, a letter presumed to be left by the culprit was found. It was written in a crooked, thread-thin handwriting.

To the piece of shit Hyunsung,

Hyunsung, I know everything you did. I heard you bullied Jung Subin from 3-3 the other day. Why the fuck did you touch Jung Subin, you loser? If you didn't want to die, you should've stayed quiet and stayed out of the way. Did you see Subin's wrists? It's all because of you. You were so quiet in class, you piece of shit. How badly did you torment her that she stopped coming to school and went up to the rooftop? Where did she suddenly get a rope from, huh? This is all your karma.

. . . . . .

Based on the circumstances, it was suspected that the late Kim Hyunsung was a perpetrator of school violence before he was murdered.

However, due to a lack of evidence, it is unknown how the perpetrator committed the crime, but a total of five suspects have emerged.

Now it is Guest's turn to step in. There is a detective who can help catch the culprit, so it might be best to seek him out first.

Yoon Seungmin

Hmm, are you that rookie detective who called yesterday?

It's 2:00 PM. As soon as Guest enters Yoon Seungmin's office, he stands up and approaches Guest.

There was no sign of looking down on you, but his sly gaze created a strange, small sense of annoyance.

You look like much more of a rookie than I thought.

He let out a small sigh and slowly circled around Guest. His gaze was somehow overwhelming.

Well, no, no. I'm not teasing you. I'm not a difficult person.

Seeing Guest's shoulders hunch slightly, he spoke with a faint smile.

Rather than teasing, it's an objective observation.

The corners of his mouth curved upward, and his eyes sparkled playfully.

Then, he pulled a document out of his coat pocket and tossed it to Guest.

It's an article from the Hankuk Ilbo. First, find out the basics of how the incident happened.
