A tense fight unfolded between Jangsung (Heo Jun-ho) and Il-do (Lee Hae Yeong), whose desires were ignited by Dong-ju.
Dong-ju is allergic to cinnamon, but he ate the sweets Jansung sent him, knowing that they contained cinnamon.
He risked his life to get revenge on Jangsung, who had driven his only sister to death. In the end, Dongju collapsed and was taken to the hospital. Seeing Dongju on the brink of life and death, Jangsung and Lee
Rud smiled in his heart. In fact, Janseon had been interested in Dongju from the beginning. In response, he urged Chairman Cha (Woo hyun) of the Daesan Group to fire Dongju, but Cha had already fired him.
Dong-ju, who was favored by Chairman Cha, increasingly rose to prominence within the Daesan Group. Meanwhile, Chairman Cha's grandson and Dong-ju's lover, Eun-nam (Hong Hwa Yeon), appears in the company.
She married Yangseong's nephew Hee-chul (played by Kwon Soohyeon) in an arranged marriage, and then Dongju's "Patriotic Fund" was hacked into with 2 trillion won of secret political funds.
Janseon was unable to use the Patriotic Fund because of Dongju's memory loss, and he was under a lot of pressure.
The method that Ng-sung came up with was to drag down Chairman Cha and put Il-do, who he could easily manipulate, in the position of chairman of Daesan Group. If that happened, he would be able to get more than 2 trillion won.
So Janseon and Ildo decide to kill Dongju, knowing that Dongju will have an allergic reaction.
However, the situation did not go as Janseon expected. Dong-ju did not die. On the day that Dong-ju was shot on the yacht, Il-do was photographed on the sea.
Eun-nam gets the video footage of the incident, and also witnesses Jang-seon's secretary Gu-ho (Choo Young Woo) at the scene of Dong-ju's sister's death.
From Eun-nam's perspective, her stepfather may have tried to kill her beloved Dong-ju, and her husband's uncle, who she married for political reasons,
It is a shocking situation that even involves the death of Dong-ju's sister. In the end, Eun-nam announces her divorce to Hee-chul and pressures Jang-seon with the video. In response, Jang-seon tells Il-do again,
He gave the order to kill Dong-ju.
