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

Young's fiancé, Lee Myeongho, is suspicious of 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 Moon Heejoo's death.

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

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

Young asks Soo to escort her at PL Group's anniversary party, but problems arise when Jin Sora 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, Jo Moocheol 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.

The date for Young's surgery approaches, and she starts cutting people off from her life.

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