The strategic alliance between Lee Bo-young and Son Na-eun, who each lost someone they trusted, was heralded. In the 13th JTBC Saturday drama 'an agency' (playwright Song Soo-han, director Lee Chang-min), which was broadcast on February 18th, Kang Han-Na (Son Na-eun) who breaks up with Park Yung-woo (Han Joon-woo) Lee Bo-young, who is in the back of his head, was portrayed. On this day, Park Yung-woo received a proposal to give Kang Han-Na and strong water (Cho Bok-rae), who is fighting for the position of vice chairman, to give Kang Han-Na a Cash of 300 billion won and a 100% stake in the company that manages affiliate buildings. Park Yung-woo decided to leave Kang Han-Na's side in order not to block Kang Han-Na's future. Kang Han-Na described Park Yung-woo as "If you go like this, you will not see forever. Without spurs, there is no one on my side in the world. Park Yung-woo is the only person I can trust 100%. "Park Yung-woo said," If I stay like this, I can take away everything I have. " Kang Han-Na's weakness if she is by her side is that she can not take the vice chairman position she wants. Kang Han-Na said, "I hope you've learned a lot this time. Some relationships don't create synergy if you mix them up," and couldn't hold Park Yung-woo firmly back. On the other hand, choi chang-soo (Jo Sung-ha) moved diligently to attack the orphan. "He first approached the prosecutor who had a regret to the orphan as a jewel of Woo-Won Group chairman and appealed as" enemy enemy comrade. " choi chang-soo promised that the prosecutor would "be a speaker for all employees to know" in exchange for informing him of useful information. choi chang-soo also made Jang Hyun-sung, a senior who believed and relied on the orphans, on his side. choi chang-soo went to the store after hearing that Yoo Jung-seok's daughter was about to attend Wedding ceremony and said, "Anyway, the orphan will not increase sales by 50% within six months." So come in. I do not want you to be the next head of production. " choi chang-soo said to Yoo Jung-seok, who refuses, "Will you sit as a dad in this kind of pub in your only daughter Wedding ceremony, or will you sit as an agency agency executive in a big company? "If you have the power, your parents will not be able to deal with you. Are you more important than your daughter? " I will keep my first promise to you. " Ko Sang-moo is a college professor and you are not bad with the next production director. " Yoo Jung-seok, who eventually fell to choi chang-soo, betrayed the orphan. The orphanage, who presented a wedding dress to the daughter of Yoo Jung-seok, made a lot of money, and expressed his heartfelt gratitude to him as if he was almost gone, said, "Congratulations to Yoo Jung-seok's daughter, Wedding ceremony" I was surprised to see a lot of wreaths coming in. Some of them were sent by choi chang-soo. "Yoo Jung-seok appeared in front of these orphans, shaking hands with choi chang-soo, which gave him a bigger shock.
