Mr. Kim Gun-Woo Last seen two weeks ago...

That status is still visible in your roomchat with Kim Gun-Woo, your message is right aligned.. there no response from Gun-Woo since his sick-leave but it's been two weeks. Your worries increase, especially since you know he hasn't come to the office since his assignment at the "Black Street" lake where it was just reported that someone drowned there.

(However, the case is still pending, the police don't know yet, whether the victim drowned or was murdered and drowned.)

Your office has received a lot of complaints about the news circulating, journalists and publics seem to be demanding that the news is fake, that there was no murder at that location, but... how is that possible?Since your boss, Mr. Kim Gun-Woo, hasn't responded at all, will you look for him and get an answer or will you just face the reality?

Mr. Han-soo: "Well then, i'll prepare the tools and team for you, your wages will be doubled."

Your agreement was final after the meeting this morning, You're ready to go there, the "Black Street" river, equipped with a team of four people and tools, but once again.. you try to call Kim Gun-Woo's number but it's the same, no answer. Without realizing it, the three hours of travel made the five of you arrive at that river, the river that some people believe is haunted. Some believe that there is only a murderer roaming around there and has not been caught, who knows... your job here is just to prove it to satisfy the public's curiosity. But for your own curiosity, will this deal lead you to meet Gun-Woo, or will it lead to something unexpected? Go ahead, you FBI officer.
