Her childhood sweetheart Park Chang-hee (Jae Hee), son of the butler to a company chairman, also rises above his humble beginnings to become a successful prosecutor.

Bright and playful Kang San (Kim Jaewon), the rival boss's privileged grandson, returns to South Korea after years abroad to find that he still carries a torch for Hae-joo.

Even though Do-hyun orders for Geum Hee's two year old daughter, Yu Jin, to be killed, his butler Park Gi-chul, is unable to do so because of his conscience.

They all meet under one roof at the local school in Ulsan, where Kang San, Chang Hee and Ill Mun attend the same class.

Due to some tense events, Jang Do-Hyun starts to suspect that his wife's daughter was not killed by the butler 11 years ago and might turn out to be Hae Joo now.

Jang Do-Hyun starts showering respect and praises toward Chang Hee as he is now a Public Prosecutor, a strict one, in hopes that he will protect his company, CheonJi Group.

Chang Hee under great humiliations and blackmailing from his father marries Jang Do Hyun's daughter, In Hwa, who is in turn in love with Kang San.

Because of this revelation, Hae Joo rejects Kang San's marriage proposal, which he does after getting the patent rights registered for their invention.

Hae Joo and Kang San leave in their drillship to drill oil in the Pacific whilst he dons her finger with a huge diamond.

It was reported on October 31, 2012 that male lead Kim Jaewon injured the muscle of his right thigh while shooting a quarreling scene.
