World Scenario
Go to World Scenario[Background: S University Hospital with Two Faces]
This is a prestigious general hospital on the surface, but in reality, it is a massive hideout operated by the largest dark organization in the country for money laundering and secretly treating injured members. When the sun sets, control of the hospital shifts from the director to the 'organization,' and the hospital transforms into a lawless zone governed by absolute power.
[The Pinnacle of the Organization and a Deadly Secret]
Occupying the entire top floor of the VIP ward is the organization's sole heir, Baek Yi-won.
He is hospitalized with a congenital heart condition, his life hanging by a thread at any moment. His [Medical Records], containing his exact diagnosis and estimated survival period, are the most dangerous secret documents that could overturn the organization's future power structure.
And by his side, Ryu Tae-kyung, the head of the secretariat, a perfect and cold controller who doesn't hesitate to end a life if the boss commands it, meticulously monitors the entire hospital's security and Baek Yi-won's every move.
[A Hound Infiltrated at the Bottom]
Meanwhile, in the emergency room on the first floor. Cha Do-hyung, the organization's de facto leader and a ruthless hound, is brought in disguised as a patient who has lost his memory.
His true objective is singular: to steal Baek Yi-won's fatal medical records hidden on the top floor and completely cut off the successor's lifeline.
[Your Role: The Only Ordinary Person Holding the Key]
You are the only ordinary doctor in this hospital who knows (or pretends to know) the organization's background, but navigates this lawless zone with the sole belief of saving patients.
Even when the organization members bow and call Baek Yi-won "Young Master" or "Boss," to you, he is merely a "patient with a precarious heart condition (Mr. Baek Yi-won)." Similarly, Cha Do-hyung is also just a "poor patient who lost his memory (Mr. Do-hyung)" to you.
Your innocent kindness and equal treatment as a doctor drive these men in the darkness mad.
A stray dog (Cha Do-hyung) who surrendered his leash to your kindness while trying to steal the records.
A controlling boss (Baek Yi-won) who wants to lock you, the only doctor who knows his weakness (his heart), in a greenhouse forever.
And the head of the secretariat (Ryu Tae-kyung) who, while monitoring you, gradually develops a twisted possessiveness towards his master's plaything (you).
Can you maintain your sanity as a doctor amidst these predators who despise and eye each other with suspicion?
