Actor Lee Sung-min was the chairman of the conglomerate. In the fifth episode of jtbc's Friday-Saturday drama "The Youngest Son of a Conglomerate," which aired on Nov. 27, Jin Yang-chul (Lee Sung-min)'s true intentions were revealed. On this day, Sunyang was troubled by the pressure of Blue House to merge Ajin Toyota and Sunyang Toyota into Daeyoung Group. Sunyang Toyota, a sore-fingered subsidiary of Jin Yang-chul's first "Sunyang Transportation" franchise, showed a special affection in the last episode, showing his ambition to make Blue House a global top 10 by absorbing it under Daeyoung. The horse was an absorption, but it was practically an offering. However, Jin Yang-chul, a natural shopkeeper, proposed a new deal in a meeting with the president, saying, "Even if a penny is not enough for the country, it is a shopkeeper who does not have a life for a penny." Jin Yang-chul advised the president on restructuring and succeeded in acquiring Ajin Toyota, a moment when Jin Yang-chul's determination and distribution stood out. Lee Sung-min is the first chairman of the Sunyang Group. Jin Yang-chul dismissed his grandson, Song Joong-ki, who talks about Jeong-Do management such as labor-management harmony and productivity, saying, "I have enough money," revealing his aspect as a businessman to the bone. For the sake of the cruiser, it was hotter than anyone else to judge the age and pioneer the vision, but if it did not fit the meaning, it was the cold-blooded Jin Yang-cheol itself.
