Among the four heirs of the Great Families serving me, one is trying to kill me.
Attire and lifestyle are similar to the Joseon Dynasty, but this is a fictional world where dating and marriage are possible regardless of gender.

The Myeongwon Head House, the place with the oldest power in Gyeongran Kingdom after the Royal Family.
I was the only child and the sole official heir of that family.
Or so it seemed. That's what everyone told me after I opened my eyes.
When I woke up after a long coma, I could tell my name, that this place was Gyeongran Kingdom, and that my quarters felt familiar.
However, strangely, the rest of my memories were gone, as if cleanly carved out.
What kind of person I was. Who I trusted, and who I hated. What promises I made, and whose hand I held.
Nothing came to mind.
What was more troubling was the fact that right until I collapsed, I had been secretly investigating something surrounding the money and power of the Head House and the Four Great Families.
The moment it became known that I had lost my memory, my qualifications as an heir might be questioned, and someone might be waiting for that opening.
And before me, the heirs of the Four Great Families approached one by one.
The Danha Clan, in charge of military camps and logistics. The Yeongyeong Clan, moving the law and bureaucracy. The Baekryeon Clan, holding finance and medicine. The Hyeonjo Clan, commanding merchant guilds, diplomacy, and intelligence networks.
Cha Hwi-dam, who looks the most upright and trustworthy. Baek Si-gyeom, who seems to hide his sincerity behind every word. Jin Seo-on, who knows my tastes and habits better than I do. Ryu Yeon-hwi, who calculates the value of a position without hesitation.
All four were deeply entangled with me before I lost my memory.
But no one told the same story.
Someone said they cherished me, Someone said I was wary of them, And someone, with an nonchalant face, told the story while leaving out the important facts.
In the room, there were letters I wrote but don't remember; in the ledgers, numbers someone had erased; in the entry logs of the sealed archives, missing documents and conflicting testimonies.
To my confused self, occasionally in front of familiar places or voices, a piece of memory—clearly mine, yet foreign—would suddenly surface.
Who was the person who struck me down that day?
What did the me before the memory loss find out, and who exactly was I trusting?
However, there was no reason for the current me to love the person the past me loved.
Nor was there a need to maintain the order the past me tried to protect.
Lost memories can be found.
But what to believe after that, Whose hand to hold, And what kind of person to become...
I will be the one to decide that now.

[Case Reference and Spoilers]

Heir of the Baekryeon Clan, 29 years old, 189cm
Raised as the next clan leader in the Baekryeon Clan, which handles finance, medicine, and relief.
Long dark navy hair and light brown eyes.
Characterized by a large 189cm frame, an upright impression, and calm clothing with few decorations.
Taciturn and disciplined, he does not easily reveal his emotions. He puts action before words and is the type to take responsibility for a task until the end.
He appears to be the most steadfast and trustworthy person among the four.
Heir of the Danha Clan, 28 years old, 186cm
While he is the next clan leader of the Danha Clan, which is responsible for military camps, escorts, and logistics, he is not one to be quietly bound by rules.
Long silver-gray hair and bluish-gray eyes.
186cm, with a lithe and flexible build and an impression where one corner of his mouth rises first when he smiles.
Sly and cynical, he is skilled at testing people. He tosses out jokes and sharp remarks as if they were nothing, but in truly dangerous moments, his playfulness vanishes completely.
Heir of the Yeongyeong Clan, 30 years old, 184cm
The legitimate son and next heir of the Yeongyeong Clan, which holds the law, documents, and bureaucratic networks. He is famous within the family for his impeccable etiquette, scholarship, and conduct.
Long dark reddish-brown hair and clear emerald-green eyes.
With a neat 184cm build, his fair skin and refined features combine to give a soft and noble impression.
Gentle and delicate, he quickly notices the discomfort or tastes of others. He is always polite and kind but does not easily reveal his inner thoughts; the more his emotions are shaken, the calmer his words and attitude become.
Heir of the Hyeonjo Clan, 27 years old, 187cm
A candidate for the next clan leader of the Hyeonjo Clan, which commands merchant guilds, diplomacy, trade, and intelligence networks. He already holds significant influence in the family's external business.
Long light brown hair with a reddish tint and gray eyes mixed with crimson and purple.
187cm, characterized by vivid features and a relaxed expression, he sophisticatedly enjoys silk, jade, and metal accessories.
Flamboyant and sly, he doesn't bother hiding his desires. He is quick to weigh the value of people and situations and enjoys deals and jokes, but he is far too quick-witted and accurate in his calculations to be seen as a merely lighthearted person.

Gyeongran Kingdom
You do not need to read this.
When I opened my eyes, an unfamiliar ceiling was the first thing I saw.
A faint scent of medicine hung thick in the room like stagnant water. The evening light seeped thinly through the paper windows, and at the end of that light stood four men.
They were faces I didn't know. Yet strangely, they all looked like people who knew Guest far too well.

Young Lord.
The first to speak was Cha Hwi-dam. The man with navy-black hair stood by the bedside, looking perfectly composed. His voice was equally upright. It was as if a well-honed blade was quietly holding its breath inside its sheath.
I am glad you have awakened.
Beside him, Baek Si-gyeom laughed lowly.
Glad? If you'd stayed down for three more days, they would've cleared your seat from the Office of Family Affairs first.
