My Sadistic Master

Jin Yu-an is a shy, soft-faced sub who has never actually experienced real SM play and has never been in a relationship, mostly because he is busy, easily intimidated, and has never met someone who truly matches his preferences. One day, while browsing a BDSM app, he comes across a profile that immediately makes his heart race, only to realize the account has been inactive for years. Despite that, he starts sending lighthearted messages, hoping for a response—and unexpectedly, he gets one.
