Jaehee, the second daughter-in-law of Sungjin group, plans to make her husband, Junhyuk, take over the highest position of power in Korea.

Han-suk holds the secret surrounding the death of Min-seon. Jae-hee, with the help of Jeong-ho, begins to dig into the background of the case.

Yoon Jae-Hee marries Jung Joon-Hyeok, an illegitimate son of the Sungjin Group, and does all she can to catapult her husband to the South Korean presidency.

Han-sook promises Jae-hee the position of CEO of Art Space Jin, but Jae-hee has no way to know her mother-in-law's true feelings. Later, she is distraught when she sees Yi-seol flirting with her husband.

Jae-hee tries to ignore Jung-ho, who has questions about the death of Young-joo. Later, Jae-hee discovers a shocking video in Sungjin's secret file.

Dong-min grows suspicious of Jae-hee, who is convinced that someone is involved in Young-joo's death. She plans to destroy Kang-hyun for standing in her way.
