Introduction of His Gumiho

Hwang In Yeop is, was and will be Cha Eun Woo's. No matter if he is a Gumiho or a human. but Eun Woo was only a teen who never experienced any love or support.

That was when In Yeop, a Gumiho, thirsty for a virgin's heart arrives. But in a thousands of years, it was the first time he felt not only desire but...love!!!
Why? The power marble of the Gumiho was swallowed by Cha Eun Woo.

What if In Yeop turns into human for the sake of Eun woo's love? But until then, Eun Woo is already a mature CEO. Will they end together?
