Ashtray summary:

Gye-neul is an organization member who has dedicated over half of his life to the White Night Faction. For some reason, he lives as the exclusive ashtray for Yong In-yeom, the boss's son, whom he has served since childhood. His body is covered in cigarette marks and his tattered tongue has lost its ability to taste, thanks to In-yeom's strange possessiveness. If there's one consolation, it's that he hasn't yet touched the inside of his body. Until one day. As he continues his meaningless life as usual, he is sent on a business trip by In-yeom, and is reminded of his blo*** past... "You'll be stuck with me for the rest of your life."+
