When Oh Young, the millionaire heiress of the PL Group, receives a letter from her long-lost brother Oh Soo, she ventures out to find him in spite of her visual disability.

When Oh Soo is mistaken to be Oh Young's brother, he quickly begins a long con in order to win her trust... and eventually her money.

Young's fiancé, Myung Ho, is suspicious of Oh Soo and runs a DNA test to prove that he is not Young's actual brother.

Soo helps Young to rejoin the outside world and confront the people she fears.

Soo and Young's trip to the beach ends abruptly when Soo forgets that it's the anniversary of Hee Joo's death.

Just as Soo acknowledges his feelings for Young, she takes steps towards marrying Myung Ho.

Secretary Wang and Oh Soo are determined to discover each other's true motives towards Oh Young.

Young asks Soo to escort her at PL Group's anniversary party but problems arise when Jin So Ra returns.

After a particularly painful spell, Young becomes increasingly suspicious of Soo's true motives and identity.

Though Young's brain tumor has relapsed, she refuses to have surgery even though Soo and Secretary Wang demand it.

After Soo desperately pleads with him, Moo Chul finally agrees to ask his sister, the country's top neurosurgeon, to look at Young.

Soo convinces Young to go through with a high-risk surgery and contemplates telling her the truth.

Although Young discovers the truth about Soo, she contemplates going along with his ruse regardless.

Soo spends his last day with Young.

Forgiveness is not easy, but Young does promise to see Soo again after her surgery - which occurs during his pivotal game against Boss Kim.
