According to the production team of KBS 2TV's Drama Suits (director Kim Jin-woo), the 4th episode, which aired on the 3rd, shows two wonderful men, Miniforce Seok (Jang Dong-gun) and Ko Yeon-woo (Park Hyung-sik) The broadcast was largely developed in two streams. One was the story of Miniforce, who was reunited as an opponent's lawyer in the old Couple and Divorce lithigation case, and the other was the story of the growth of Ko Yeon-woo, who was able to break his shell by himself. Two different stories of different personality were exquisitely intertwined and gave various fun to the house theater.Minorce faced Na Ju-hee (Jang Shin-young), who was a Couple during his past inspection, in court. Coincidentally, the incident they faced was the Divorce lithification of the chaebol. It seemed like a divorce lithigation of a tycoon, a divestment of astronomical property, a custody battle, but the reality was different. Miniforce got a hint of 'real love' through Ko Yeon-woo, and eventually won the victory without going to trial as always. In this process, the past of Miniforce was also revealed. The hint of why Miniforce had to quit the exam and why he had broken up with Na Ju-hee, the two reunited after 13 years, felt a bit of affection, but decided to walk their own way coolly. In this process, the unexpected aspect of Miniforce stone was revealed and the audience was excited. In the meantime, he was a man who could always win a game and put down a lot of confident Miniforce seats for love. Chae Geun-sik (Choi Ki-hwa) had previously pinned the neck of Ko Yeon-woo for the past. Chae Geun-sik also led him to meet with BewhY. But with his unique empathy, Ko Yeon-woo, who was close to BewhY, led him to sign his mentor Miniforce, who gave Chae a pleasant blow. Ko Yeon-woo, who spoke to Chae Geun-sik leisurely, saying, I will not be dragged around, was thrilling and pleasant, and Ko Yeon-woo also caught the heart of Ada Lovelace (Son Sook), one of the major customers of the law firm Kang & Ham. Ada Lovelace, the craftsman of traditional chapters, canceled the United States of America contract, fearing she could not spend time with her children and children. Again, Ko Yeon-u brought together all of Ada Lovelace's children and grandchildren. It was not a plan, but the ship’s grandchildren broke the gut, and Ada Lovelace realized how precious it was to soak the gut. Eventually she re-promoted the United States of America corporation contract - which was thrilling, too.
