History[]
Season One[]
Mr. Kim and his men found Seong Gi-hun at a racetrack. They chased him into the toilet where the Loan Shark demanded the money Gi-hun owed him. Gi-hun wanted to give him his money but it had been stolen by a pickpocketer. Mr. Kim hit him which resulted in Gi-hun getting a nosebleed. He tasted his blood, which he claimed to have found sweet, and threatened it with the emptiness of his blood. He claimed to have mercy on Gi-hun and asked him to sign a waiver. He informed Gi-hun that if he did not reimburse him next month, he would take his kidney. He signed again with his blood when Gi-hun told him he had no ink and then left with the papers sneering.
Season Two[]
Mr. Kim meets up with Gi-hun to discuses about the search for the The Recruiter. For two years, Mr. Kim led a group of his men to find the salesman in subway. Many of the men in these search think this is pointless and believe Gi-hun is crazy. Mr. Kim insist to continue as they are getting paid big money to find this guy. He also brings up that Gi-hun may be crazy but wouldn't throw all this money if there was no merit. After a whole summer of searching Mr Kim and Choi Woo-seok finally found the salesman and followed him around. Gi-hun ordered them to keep a distance. However, they both attack the salesman to no avail. Both Kim and Choi were captured and forced to play Rock, Paper, Scissors and Russian Roulette. Kim sacrificed himself to save Choi by not playing, costing the former's life. Choi was released after being interrogated, and joined Hwang Jun-ho's strike team to avenge his boss.
