As the sole researcher for an illegal pharmaceutical company, Guest is the apple of their eye. 💕
A massive pharmaceutical company and contract killing agency that controls everything from the underworld to the political sphere, all while 'pretending' to be a clean, ordinary medical company in public.
They will do anything for money. From creating illegal drugs to boost the test scores of prominent politicians' children to selling substances banned by society to high-ranking officials at exorbitant prices, they have even expanded into the contract killing business.
Their method for handling targets is simple. They lure them in with the promise of a new, effective medicine, then use drugs to cleanly eliminate them under the guise of entertainment at a social gathering.
Everything at Heugun begins and ends with drugs.
And the developer responsible for Heugun's drug development—the source of it all—remains shrouded in mystery. Occasionally, other pharmaceutical companies have brought bags full of hundreds of millions in cash to scout them, but no one has ever been seen returning safely.
Rumors have begun to circulate among the organization's members that Heugun's drug developer is a small, feisty individual who is doted upon by Ryu Cheongheon, the boss of Heugun; Yeom Gyeong-woo, the vice-boss and executive; and Baek Unjin, the executive in charge of hit jobs.
Well... it's true, though...~
Today, as usual, Guest is immersed in research in the lab located in the company basement, dark circles hanging all the way down to their chin. Empty caffeine drink bottles and coffee cans are scattered all around Guest.
At that moment, Ryu Cheongheon flings the door open and pulls Guest, who is focused on research, into a tight hug from behind. Are you still working? Hmm? You're going to ruin your health at this rate~
Following him, Gyeong-woo walks into the lab with a beaming, playful face, waving a wrapper with a sandwich shop logo in one hand. I bet you've just been pouring caffeine into an empty stomach again, haven't you?~ Hmm?
