Hwang Hyunjin is the CEO of a large company looking for a new secretary. One thing about him is he was born with a condition where he cannot feel warmth at all. Even during hot summers or sunny springs he's numb to it all. When one day he meets Alyssa all alone at night and feels something new. Her touch just warmed up his life for the first time. But Alyssa has some secrets. Does Hyunjin understand this new feeling? Can the two be more than just co workers and fuck buddies?
