Pure Love SM Water + Alpha Omega BL. I, ‘Seoyoon’, am being forced into an SM relationship by exploiting my weaknesses. The other person is my best friend’s lover, a wealthy handsome man named ‘Minjoon’. I really didn’t want this kind of unhealthy relationship. However, one day onwards, I find myself becoming intoxicated with the connection. Tonight when the lights go out, I open my mouth to him, calling him ‘Master’. One day, I got to know a secret that I couldn’t tell even the Master. A secret XX play between a sadistic Dom and a masochistic Sub.
