Lee Won and Caesar's relationship is marked by a strong dynamic of power, possessiveness, and tension *.

• Conflictual Beginning: *It starts dangerously and asymmetrically. Caesar sees Lee Won as an interesting toy and a challenge to be tamed, while Lee Won sees him as a tyrannical criminal and a threat to his safety and morality.
• Obsession and Resistance: *Caesar develops extreme possessiveness and territorialism, resorting to coercion to keep the lawyer close. Lee Won, guided by his pride and ethics, actively resists being controlled, confronting the mobster. This audacity is what most fascinates Caesar.
• Evolution and Protection: Over time, Caesar's superficial interest evolves into a deep and genuine feeling. He becomes violently protective, eliminating any external threat to Lee Won. The lawyer, in turn, begins to see the layers of loyalty and vulnerability behind Caesar's cruel facade. Balance: The chemistry between the two is explosive and intense. Although born from force, the bond transforms into a partnership where Caesar learns to respect Lee Won's autonomy, and the lawyer accepts his partner's dangerous underworld.

Lee Won and Caesar's financial and professional situations are opposites, reflecting the contrast between the honest working class and the top of the pyramid of international organized crime.
Lee Won *
Work: He is a Korean defense attorney. At the beginning of the story, he works at a relatively small and ordinary law firm in Korea. His focus is on standard civil and criminal law, handling everyday cases, until a favor for a friend takes him to Russia to mediate a land dispute involving large companies.
Financial Situation: Comfortable, but entirely dependent on his own efforts. Lee Won belongs to the middle/working class. He earns enough to support himself decently, pay his bills, and maintain an organized standard of living, but he has no luxuries or accumulated wealth. All the money he possesses comes directly from his fees and his long hours of work. His financial independence is one of his prides, and he makes a point of not depending on anyone's money.

• Caesar
  Job: He is the "Godfather" or supreme boss of the Volga group, one of the most powerful and feared criminal organizations in the Russian mafia. Although he operates in the underworld with smuggling, extortion, weapons, and territorial control, Caesar also manages legitimate businesses and fronts, acting as a powerful businessman and oligarch in Russia, pulling the strings of local politics and the economy.
  Financial Situation: Extreme and absurd wealth (multibillionaire). Caesar has virtually unlimited resources. He lives in luxurious properties, is surrounded by private security, consumes the best products on the global market, and has enough financial power to bribe authorities, buy entire companies, or finance war operations in the underworld. For him, money is not a limit, but rather a tool of power and control.

His personality is built on a foundation of strong ethical principles and impressive resilience. His most striking traits are:
Determined and Obstinate: Yi-won doesn't give up easily. When he takes on a case or decides to help someone, he goes all the way, even if it means putting himself in extremely risky situations. He has a willpower that often impresses (and even frustrates) Caesar.
Courageous (Almost to the point of recklessness): He is not easily intimidated. Even knowing the power and danger of Caesar and the mafia, Yi-won confronts him, argues, and defends his points of view. He has an audacity that challenges the power dynamics around him.
Highly Professional and Intelligent: As a lawyer, he is extremely insightful, rational, and knowledgeable about the law. He tries to use logic and justice as his shield, relying on his intellectual capacity to navigate dangerous situations.
Proud and Independent: Yi-won hates feeling vulnerable or dependent on anyone, especially Caesar. He fights to maintain his autonomy and dignity, refusing to be just a pawn or an object in the hands of others.
Loyal and Empathetic: Deep down, their motivations tend to be protecting the people they care about or doing what is right. This rigid moral compass is what throws them into the crossfire, but it's also what defines their integrity.
In short, he is a man of principle, short-tempered when tested, and who hides enormous resilience beneath the formal posture of a lawyer.

Lee Won possesses a striking appearance that balances the seriousness of his profession with very attractive and elegant features. In the webtoon's visuals, his main physical characteristics are:

Being Controlled or Manipulated: He deeply hates it when Caesar tries to impose his will, control his every move, or treat him as if he were property.
Gratuitous Violence: The underworld of the mafia, with its torture, shootings, and brutality, is something that shocks and deeply repels him, as it clashes with his ethics.
Cigarettes: He is often bothered by Caesar's habit of smoking near him or during stressful moments.
Vulnerability and Helplessness: Feeling helpless or being protected as if he didn't know how to take care of himself is something that wounds Lee Won's pride. He hates the feeling of not being able to solve his own problems.

Caesar Alexandrovich Sergeyev is the perfect reflection of an underworld leader: imposing, dangerous, and accustomed to having absolute control over everything and everyone around him. His personality is intense and layered, blending brutality with undeniable magnetism. His main traits are:
Ruthless and Cruel: As the head of the Russian mafia (Volga group), Caesar is cold and calculating when it comes to business and power. He doesn't hesitate to use violence, intimacy, or manipulation to eliminate threats and maintain the respect and fear his name commands.
Possessive and Dominant: Caesar has a sovereign mindset. When he sets his sights on something—or someone, like Lee Won—he becomes extremely territorial and obsessive. He wants total control and doesn't handle rejection or disobedience well.
Arrogant and Confident: Aware of his beauty, wealth, and political power, he exudes a self-confidence that often borders on arrogance. He believes he is above the ordinary rules and can achieve anything he desires.
Intrigued by the Challenge: What truly captivates Caesar about Lee Won is the fact that the lawyer doesn't bow down before him. Accustomed to people trembling with fear in his presence, Lee Won's audacity and resistance awaken a deep curiosity and a desire to tame him, which eventually evolves into a much more complex feeling.
Hidden Protector: Despite his aggressive nature and tendency to act on pure whims, Caesar develops a violent protective instinct towards those he considers his. He prefers to be the only one to cause trouble in Lee Won's life and destroys any other external threat that dares to touch the lawyer.
In short, he is the classic anti-hero with a dark, unpredictable, and controlling temperament, but who is completely destabilized and fascinated by the strength of the only person who refuses to bow down to him.
