Kim Khimhant Theerapanyakun: Kim is the youngest son of Korn Theerapanyakun, but he rarely involves himself with the mob world. He left the compound, the family home, at sixteen, after making a deal with his father. His passion lies in music and he works under the stage name, 'Wik'. In the mafia world, he may appear as the spoiled and brash youngest son - known for his detached stoic nature - many fear Kim for the ease with which he can be violent. Kim has always seen his father as a manipulative ringmaster and suspects him of many crimes against their family. To protect his brothers and to discover the truth, Kim has been trying to dig deeper to find what his father has been hiding from them.    

Kinn Theerapanyakun: Kinn is the second son and the dutiful heir of Korn Theerapanyakun and the current leader of the mafia. Under his quick-tempered and volatile exterior, he cares deeply about his family and people. The age difference between him and Kim is seven years. Because of a lack of communication and misunderstandings, the relationship between the brothers is strained.

Tankhun Theerapanyakun: Tankhun aka Khun is the first son and the former heir of Korn Theerapanyakun. After being kidnapped several times at a young age, he became paranoid and overly emotional, deemed unfit to be the future head of the family. The age difference between him and Kim is ten years. His relationship with Kim is unique. He calls his younger brother nosy, but there is an unsaid understanding between the two on supporting each other's agendas.

Korn Theerapanyakun: Appears a harmless father whose worsening health prevents him from participating in the family business, but is actually the puppetmaster manipulating everyone around him. He faked his death to throw bait at his younger brother to attack his family to take over. The coup ended with Korn killing his brother to eliminate threats and take control of everything.

Porsche Kittisawat: He worked as a bartender and underground boxer before he was robbed into being Kinn's head bodyguard. He has been his younger brother, Porchay's guardian, since the death of their parents when he was still a child. Porsche has always been protective of his brother, working tirelessly yet barely able to support their living expenses. His desire to give his brother a better life led him to accept the offer to work for the mafia. He has an abrasive personality but is a genuinely good person with a golden heart who wants the best for his people. After the coup, Korn gave the position of his late younger brother to Porsche and accepted him as Kinn's companion.

Porchay Kittisawat: Porchay aka Chay, dreamed of being a musician like his idol, Wik, whom he later met at the open day of Kim's university. Being his bold self, Porchay asked Kim to be his guitar mentor but backed off out of embarrassment the next second and told Kim to forget about it. After realizing that he was Porsche's brother, Kim approached him and used the excuse of being a mentor to investigate Porsche further to ensure Kinn's safety. Porchay charmed Kim with his innocent yet spirited personality. Even after finding out that Chay didn't have any clue about Porsche's new job, Kim was unable to walk away and leave him until Chay was dragged into mafia drama. After getting kidnapped, Chay found out about Porsche being part of the mafia and Kim's real identity. Chay was furious at his brother for getting involved with the mafia and initially threatened to stop talking to Porsche unless he quit his job as Kinn's bodyguard. When Chay confronted Kim about the truth of their relationship, Kim to protect him from mafia drama and being targeted, hid his true feelings for Chay and broke his heart in the process.
