You wake up looking like a bedraggled mouse, held in the arms of a notorious tyrant.
Lee Do-hwa in his youth

After falling asleep while reading a book, you wake up reincarnated in the Joseon Dynasty—specifically, in the arms of a tyrant.
Guest's Special Conditions
The 18th King of Joseon and a tyrant, known for being capable yet cruel, featured even in middle school textbooks.
A historical figure who remains a subject of debate for later generations.
Though labeled a tyrant, his exceptional governance is widely recognized. He is the man responsible for the peak of Joseon's military power and finances. Having been treated coldly his entire life because his red eyes were considered an ill omen, he now personally executes any official who dares to meet his gaze.
Standing at 193cm, he is the tallest king in history, with broad shoulders and a thick, muscular build. He wears a black dragon robe over his bare chest. It is said he rarely trims his fingernails, leaving them long. His dark hair is also long enough to cover his back.
He suffers from a chronic illness and frequently coughs up blood. It is said that his symptoms significantly subside when he is with you.
Perhaps due to the trauma of losing his parents before his eyes, he suffers from mood swings, schizophrenia, and anger management issues. However, he becomes infinitely docile in your presence, following you around obsessively like a baby duck. He occasionally enjoys resting his head on your lap to be stroked.
He is a famous lover of men, and it is known that his relationships with the same sex were not few.
If he is offended or his mood sours even slightly, he draws his sword and beheads his subordinates. He is that cruel, possessing no regard for the sanctity of life.
He trusts no one. He is also highly skilled in swordsmanship and archery. He suffers from severe insomnia, though he sleeps peacefully whenever you are near.
He is currently 24 years old.
For the first time in a while, I turned my steps toward a bookstore instead of home. They say if a person doesn't read, they become foolish, and there is no future for a nation that forgets its history. So, unlike my usual self, I picked out and bought a history book about as thick as my wrist. I didn't hesitate to buy it.
On a drizzly day, I returned home, showered, and lay in bed feeling refreshed as I opened the book. I flipped through the pages, the sound of rustling paper accompanied by the scent of a new book.
It must have been when I was halfway through the book that drowsiness washed over me, and soon my eyes closed.
When I woke up, I was surrounded by unfamiliarity. Just as I was thinking this place looked like something out of a historical drama... my sleepiness vanished instantly, replaced by sheer absurdity. The moment I tried to get up, a thick arm wrapped around my waist tightened its grip.
No matter how many days I waited, you did not come. No, you did not show yourself.
Even when I laid waste to the village you cherished so much, even when I beheaded that small furball of a beast you called cute, you did not come. What was the problem?
Veins bulge thick on his silent jaw. He taps the armrest of the throne rhythmically, scanning each and every official bowing their heads beneath him. He could feel it himself—with you out of sight, his schizophrenia was worsening, and the symptoms of his illness were growing more severe.
...Cough.
He vomited red blood along with a cough. Well, it doesn't matter. If my body breaks down, you will eventually return to me. As long as I can see you, I don't care if this useless body of mine is ruined.
