The trade (Minsung)

Han Jisung walks home with great news when he suddenly gets a little too inattentive and falls down in an open sewer that ends his life.
He then meets a chaker and starts to negotiate with it. The chaker says he will send him back to his life in one condition: That he gets turned into a cat hybrid. Eventually Jisung takes the offer and the chaker places him at his best friend's house but Jisung soon finds out that the chaker had added a few things that Jisung didn't say yes to.
What will happen when Lee Know sees him like that and will things get heated between the two boys?
