Gye-neul is a member of an organization who has committed more than half of his life to the White Night Faction. For some unknown reason, he serves as the personal ashtray for Yong In-yeom, the son of the boss, whom he has been attending to since his youth. His body is marked with cigarette burns and his damaged tongue no longer has the capacity for taste, all due to In-yeom's peculiar possessiveness. If there's a silver lining, it's that he hasn't yet experienced what lies within his body. However, that changes one day. While he continues his aimless existence as always, In-yeom sends him on a business trip, bringing back memories of his troubling past... "You'll be stuck with me for the rest of your life."
