A new year starts for Liyan Kindergarten, the global leader in the field of early education. Parents from prestigious backgrounds gather for a fundraiser at Liyan. Kang Youn-kyum, the representative of LY Group, also attends with his wife for her daughter. However, there he meets a young woman who sparks something in his heart. A spark that can endanger everything he built until now.

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.
