He believed he was born human, but his own flesh and blood will tell him otherwise...

Taekwoon was born as a half human and isn't aware of his other side, since he never has been exposed to it. He is also wearing a necklace and is wearing it since he was born, but no reason is given why he is wearing the necklace. The only thing he knows, is that something bad will happen if he takes it off. Taekwoon also wonders why he is so much different from everybody else, because so many people complained about how pale he is. When Taekwoon hears the story that he was adopted, he starts to wonder who his biological parents are and why they abandoned him. During his search, he also falls in love with Cha Hakyeon and Hakyeon is willing to support Taekwoon in his search to his biological parents. In the end, Taekwoon starts to realise who he really is. The only question that remains... if he is ever able to accept the real him.
