The Youngest Son of a Conglomerate' Song Joong-ki was killed by J. Y. Park, and Conglomerate opened his eyes as the youngest. In JTBC's "The Youngest Son of a Conglomerate," which first aired on the 18th, Yoon Hyeon-woo (Song Joong-ki), head of Sunyang Group's future asset management team, was depicted. Jinyoung (Yoonjae Moon) was sentenced to probation for embezzlement and Yoon Hyeon-woo prepared a cruiser event. JIN SUNGJOON (Kim Nam-hee) went to Jinyoung and said, "I will not be able to do my father's succession. I will give up my inheritance. It's over now, "Jinyoung said," It's a scary law for a person who is a subject of pride. "He caught JIN SUNGJOON. JIN SUNGJOON shook Jinyoung's hand and Jinyoung suddenly fell down complaining of difficulty breathing. Yoon Hyeon-woo witnessed this scene and JIN SUNGJOON ran out of his seat. Jinyoung underwent emergency surgery for acute myocardial infarction, and this news was only available to the Sunyang people. Mo Hyun-min (Park Ji-hyun) called Yoon Hyeon-woo aside and ordered him to visit JIN SUNGJOON, who ran away, saying that the announcement of the special statement was made by JIN SUNGJOON instead of Jinyoung. JIN SUNGJOON, who was hiding in the hotel, wielded a golf club in front of the staff, and Yoon Hyeon-woo found such a JIN SUNGJOON. Yoon Hyeon-woo tried to persuade JIN SUNGJOON to take him to the Event. Yoon Hyeon-woo told JIN SUNGJOON, "What happened before the president fell will never be known outside. I will never open my mouth. "Thanks to Yoon Hyeon-woo, JIN SUNGJOON solidified his position at the event. Shin Hyun-bin seized Sunyang products, and Yoon Hyeon-woo visited Seo Min-young. Seo Min-young said, "JIN SUNGJOON vice chairman did accounting for illegal succession," and Yoon Hyeon-woo denied it effortlessly. However, Yoon Hyeon-woo knew about the raid and took action: the computer was a new product and all the documents were promotional materials. Jinyoung's surgery was successful, but he needed absolute stability. "Jinyoung's fourth son, Kim Young-jae, and his wife Lee Hae-in (Jung Hye-young), who had been isolated from the family, came to visit. Lee Hae-in said, "I brought 3% of Sunyang's shares. My stake in the Sunyang management battle will be a casting fight." When asked, Lee Hae-in said, "What are the conditions?" I need to know the truth of the accident that day. You know. Bring me the answer. Then I transfer all of my shares. " Shin Kyung-min (J. Y. Park) told Yoon Hyeon-woo that he found a document that was not on the list while he was disposing of the material. This document is related to Sunyang's paper company. Yoon Hyeon-woo reported to the general manager, "Someone is taking a large amount of pure assets overseas through this ghost paper company," and the general manager immediately shredded the document. However, Yoon Hyeon-woo informed JIN SUNGJOON that Yoon Hyeon-woo suggested "move ahead of the prosecution" and attribute assets that went abroad to the assets of Sunyang Products. JIN SUNGJOON, who heard them, informed the general manager who came in with good timing, "Yoon team leader brought something interesting." Nolan Yoon Hyeon-woo lied to JIN SUNGJOON, "Where is the original document?" JIN SUNGJOON instructed Yoon Hyeon-woo, "As of today, I am appointing you as the head of the finance team. Find the assets of Sunyang that have been leaked abroad." JIN SUNGJOON said, "So now I have to have something in my name. I will have the light of a new cruiser. I want my father to take the dark shadow of the sun." Yoon Hyeon-woo, who went overseas under the direction of JIN SUNGJOON, received $600 million in his own account. Meanwhile, Seo Min-young (Shin Hyun-bin) obtained a conversation between JIN SUNGJOON and Yoon Hyeon-woo recorded by Jin Jinyoung (Kim Shin-rok). On the way back after getting the money, Yoon Hyeon-woo felt a strange sensation. Someone chased Yoon Hyeon-woo and Yoon Hyeon-woo felt it. Gunmen blocked Yoon Hyeon-woo's car, and Yoon Hyeon-woo made a mortal escape, apparently succeeding in escaping, but Yoon Hyeon-woo collapsed under the influence of drugs. Shin Kyung-min appeared in front of Yoon Hyeon-woo who was kidnapped. Shin Kyung-min said, "Didn't the team leader tell you not to reject the orders from the top, don't ask questions, and don't make any judgments? I just followed them." When asked, "Who did this to you?", Shin Kyung-min answered, "This is who I need." Yoon Hyeon-woo was shot and fell into the sea. When I opened my eyes, Yoon Hyeon-woo was in the car of Kim Young-jae and Lee Hae-in. Yoon Hyeon-woo said, "Why did my body become like this?" Lee Hae-in called Yoon Hyeon-woo Do Jun. Yoon Hyeon-woo became Jin Yoon-ki and Lee Hae-in's second son, Jindo Jun.
