Eun-pyeong climbs higher in politics. Despite his success and popularity, he still remembers everything about Ra-el and her real mother even after all these years. Knowing in his gut that Ra-el is still alive, he continues the search. Meanwhile, Youn-kyum feels his heart burning when he thinks of Sun-bin. Although his emotion is about to burst, he has no intention of fighting it.

While satisfying Dam-ri and Ji-hee, Sun-bin approaches So-ra at the same time. With her charms and wit, she manages to obtain So-ra’s trust. Sun-bin and Jin-wook get invited to Sewoonjung, Youn-kyum’s personal party where not anyone can join. By using this big step, Sun-bin moves forward with her plan of vengeance for her true identity, Ra-el.

Sun-bin is on a clear path to gaining So-ra’s total trust. With the trust she gains, she must investigate the ledgers of LY Group that might be in Youn-kyum’s study. However, Eun-pyeong finds shocking information about Kang Youn-kyum. Something that Ra-el has no clue about and something that can ruin her plan of taking down LY Group.

Youn-kyum does not fall for Ra-el easily. Just when things seem to be in a tight spot, Ra-el comes up with a plan by using So-ra’s birthday. Meanwhile, although Eun-pyeong is well-known for not taking any politician or conglomerate’s side, he is willing to do whatever he can to help Ra-el achieve her goal. Step by step, she becomes closer to punishing all those who destroyed her family.

So-ra is enraged with Youn-kyum’s disappearance. Despite the presence of her daughter, she does not control her emotions. Meanwhile, Youn-kyum confesses his true feelings to Ra-el. With true love as his source of energy, he determines to break free from being LY’s puppet. Ra-el’s revenge begins to speed up. The day of vengeance is soon to come.

Now that Ra-el knows about her mother Jin-sook's death, she seeks revenge by getting close to Youn-kyum. Ra-el sees his scars. She knows it isn't right, but she can't resist and slowly falls for Youn-kyum. Eun-pyeong teams up with Pan-ro to help Ra-el. Meanwhile, So-ra's compulsive behavior goes out of control when she suspects Youn-kyum is seeing another woman.

So-ra uses the hit-and-run accident to her advantage and begins to search for Youn-kyum's mistress. Ra-el keeps her distance, hitting Youn-kyum and So-ra mentally. And as soon as she disappears, Youn-kyum yearns for her even more. Meanwhile, So-ra kidnaps Ra-el's bodyguard to find Youn-kyum's woman, and a fierce battle of nerves begins between So-ra and Ra-el. Later, Ra-el makes her return dressed lavishly.

Youn-kyum and So-ra don't react as Ra-el expected. So-ra starts to ostracize Ra-el at the kindergarten now that she knows Ra-el is Youn-kyum's mistress. Ra-el starts to become anxious, seeing no difference in Youn-kyum and So-ra's relationship. Meanwhile, Eun-pyeong takes the president's chief secretary position and vows to help Ra-el get her revenge as his love for her grows deeper.

Ra-el falls deeper into the darkness after Moon-hee's betrayal and Youn-kyum's indifference. To get Youn-kyum to move, Ra-el deals with him coldly, grabbing and letting go of his heart. Later, at LY Shopping Mall's formal gathering, So-ra falls into Ra-el's plot.
