Luhan is not like everyone, since he was young, he can see how people are going to die or when is it.
He is exceptionally talented and smart.
Everything about him is good.
He is like an angel, which is absolutely not true.

Luhan is a Shinigami in Training,
his mission is to look for the ten souls that is worthy to write on his book, the Black Book.

One of the ten lives Luhan choose is Kim Jongin, he is a seer,
someone who can see the future. Everyone thought that he is a demon's child,
someone cursed,
because in the 21st Century of Seoul,
who might be able to see the future? No one.

Kai is a Seer, his life is full of regrets knowing what is the future,
in order to lift the curse, he needs 10 people who will change by knowing their future.

When Luhan and Kai met, they decided to help each other, but Luhan saw Kai's clock life...

Will there be a happy ending?
