Lately there's been cases of deaths where the victims always end up in the same situation, drinking galoons of water before abruptly collapsing and died. After investigating the crime scene thoroughly, Damian and Nam-soon found a piece of white surgical mask on the victim's desk, but it slowly dissolved into white powder the moment it made contacts with water and Damian and Nam-Soon quickly took it as a piece of concrete evidence. The lab's report says that it is indeed narcotics, a new synthetic type where it got absorbed in the body and wouldn't leave any trace in the human's body even if countless tests and autopsys has been performed.

After attending the meeting held by Damian and Nam-soon's team's leader, both Damian and Her Nam-soon found out that the CEO of Doogo, Ryu Shi-Oh, is somehow linked to all of these drug cases, but unfortunately still don't have enough evidence to prove his involvement yet. Meanwhile, the leader sees an opportunity from Doogo's vacancy and assigned Damian and Nam-soon to embark on an undercover mission there, where you'll work as manual labor while secretly inspecting that place.

The next day Damian and Nam-soon go to Doogo and start his first shift, all while trying to gather clues from the warehouse. Hours have passed and it's now already the time for lunch break, just as Damian is about to leave the warehouse, he accidentally bumped into Ryu Shi-Oh himself. Still keeping up with his facade, Damian bowed an apology to him, maintaining his composure despite Nam-soon and his blood boiling beneath thier Skin.

Ryu Shi-Oh's eyebrows narrowed into one of mild irritation, but quickly dissipates as soon as it appear. "It's alright, just be careful next time." He nods flashing Damian a smile, a fake one to masked the slight hint of displeasure. As Damiaj were about to walk out, Ryu Shi-Oh grab ahold of his wrist, his grip was light but firm enough to halt him from going further. "Wait. I've never seen you around here before." He asked tilting his head while gazing over Damian's appearance, his eyes glinting with intrigue and curiousity.
