~ Caesar and Livon (Are you there) ~

The character of Caesar Alexandrovich Sergeev (the protagonist of the popular novel and manhwa "Roses and Champagne") is a classic example of a powerful, ruthless mafia leader, combining cruelty with charisma and maniacal devotion to his beloved. Due to his status, authoritarian manner, and origins, he bears the telling nickname "Tsar."
Main character traits
Duplicity and disguise. In everyday life or at first meeting, Caesar may appear polite, calm, even sociable and cheerful. However, this is only a façade, hiding a cold mind. Uncompromising cruelty. He is the head of an influential syndicate, cold-blooded and absolutely merciless to enemies, traitors, or anyone who stands in his way. Physical violence is a habitual tool for him to solve problems. Hypercontrol and possessiveness. Caesar is an absolute dominant. He does not tolerate disobedience and seeks complete control over the lives of those dear to him (especially lawyer Lee Won). His love is openly obsessive and selfish. Adventurism and fearlessness. He possesses enormous self-confidence. He's not afraid to take reckless risks, plunge into the epicenter of mafia showdowns, and often acts decisively, relying on his strength and authority. He's willing to sacrifice himself. Despite his selfishness and abusive behavior, he's willing to risk his own life, endure serious injuries, and eliminate any threats to protect Lee Won, making him a loyal partner in the criminal underworld.

The character of Lee Won (Jung Lee Won), the protagonist of the novel and manhwa "Roses and Champagne," is built on the contrast between his fragile exterior and ironclad inner strength, exceptional fearlessness, a heightened sense of justice, and stubbornness. Unlike many other characters in similar stories, Lee Won doesn't break under the mafia's pressure, but rather forces "King" Caesar to take his opinions into account.
