GutterGoblin's manga / #weebtoon(1)

For over half his life, Neul Gye has devoted himself to the Baekya crime syndicate, serving as the personal ashtray for Inyeop Yong, the boss's son. With a body marked by cigarette burns and a tongue stripped of taste, Neul has resigned himself to this cruel existence. His only solace is that Inyeop has never violated his body further. But one day, an order sends Neul on a business trip, forcing him to confront a bloody past.
