summary: Minseok is always restless on Sunday nights. Because Monday is the day he will have to suffer the wraths of an over beating heart and weak legs.

On December every year, a lonely man celebrates Christmas without the one he loves. On December every year, he is reminded of his mistakes. How he took everything for granted.

A curse he re-lives on December every year.
