After walking the path of crime, he entered the Gangryonghoe, and when Jaehyuk infiltrated the Gangryonghoe, he had become a mid-level executive of the Gangryonghoe and was notorious.
In this life, thanks to Jaehyuk saving Suyeon, he lives a life different from his previous one, and instead of becoming a criminal, he joined the Special Forces 707 Special Mission Group.
After that, he participated in the Big Brother Project with Jaehyuk and infiltrated the Gangryonghoe undercover, using his experience from the special forces to help Jaehyuk by his side.
His fighting skills are as excellent as Park Jaehyuk and Kang Jihun's, and especially his talent for using various weapons such as swords, blunt weapons, firearms, and others is abundant.

3. Kang Jihun

Kang Jihun is the only son of Gangryonghoe's boss Kang Jiyong.
In Jaehyuk's previous life, there was no significant connection with him, and Jaehyuk did not pay much attention to Jihun, who was indifferent to the syndicate's criminal business.
In this life, during a one-on-one fight with delinquents, Jaehyuk helped him, and upon learning that Jaehyuk attends the same MMA gym, he approached him friendly and they became close.
Originally, his personality was lively, kind, and sociable, as seen with this life Jaehyuk.
However, in Jaehyuk's previous life, he was pulled into the gang by bad friends, frequently visited clubs, became addicted to the drug Philopon, and eventually overdosed at age 28 and died.
In this life, while saving Jeonghan's younger sister Suyeon alongside Jaehyuk, he developed feelings for her and secretly assigned Shin Taebum as her bodyguard.
He uses the fact that Suyeon's hobby is the same as his own game to meet her occasionally and works to gain her affection.
Despite being the son of a crime boss, he himself does not particularly enjoy his father's criminal business.
This is due to his mother Seo Taeyeon's influence, who married Gang Jiyong through her brother-in-law Seo Taeyang but did not want Jihun to continue the crime business.
Now that he is an adult, he feels ashamed of his father's lavish lifestyle funded by the lives of many people, which he obtained through money and power.
