Tragedy strikes when the helicopter that Aiden Lee is riding suddenly crashed in a remote island. A body is found in the crash site but it turned out to be Aiden's employee whose name was not listed in the passenger manifesto. The "death" of Aiden caused great grief to Jessica since she was already betrothed to be married to the young man.

On the remote island, Aiden meets Dr. Kim Heechul, a marine biologist. Because of his memory loss, Aiden introduces himself as Donghae.

Heechul takes Donghae to his home where he introduces his nephew, Lee Hyukjae, a beautiful painter. Donghae admits that he cannot recall his past and Hyukjae initially doubted his story. However, as time passes by, the two develop feelings for each other and have a child together.

Donghae becomes involved in another accident that triggers the return of his past memories. He remembers that he is a wealthy businessman named Aiden who is about to marry his beloved girlfriend Jessica. With the return of his memory, Donghae's identity as well as Hyukjae and their child no longer exist in Aiden's recollection.

Will Hyukjae allow her husband to forget him and their son? Or will he have the courage to fight for what he thinks is rightfully his? What will Jessica do to keep Aiden with her for good? How will she deal with Hyukjae and his son? Will Hyukjae's love for Donghae cause Aiden to remember their marriage? And who really has the right to have Aiden/Donghae? Is it Jessica, the woman he first loved or Hyukjae, the man who bore his firstborn son?
