Hated by those around him for seemingly bringing bad luck wherever he goes, Ren Xi unwittingly makes a pact with a witch named Nyx to save his sick mother. But there are consequences... If only Nyx could remember them! It doesn't help that she has amnesia, either. It seems there’s something more to Ren Xi’s "jinxed" past, too... something scarier than even a witch, and they'll need each other to get through it.

What happened that day was their worst nightmare... A boy escaped from home with his adopted younger sister. From then on, they were known as the children of a murderer and depended on each other to live. Growing up with each other's company, the two start harboring feelings for each other on someday that nobody ever knew...
