Not a novel reader but– . . . . . . . . . . . . It's the ML ofc. MC didn't know who the man at the beginning was because he wasn't informed anything about the client and since he was wearing a blindfold that time, he couldn't tell that that man was the ML. He could remember the ML's pheromones tho(i think).
Hiii, I'm currently at Chapter 15, and I'm really curios, who's that man at the beginning the rut partner of seo jian? is it the ML or other man?
