Jurion (i don't remember his spelling.) it's him.. I am sure because in that chapter they showed the eyes of the guy of the black outfit and his eyes matched with that jerk.
I'm thinking jealous boy, mad scientist or plot twist the madam's apprentice the blue/green hair boy
Jurion appeared in which previous chapter?I completely forgot there was a guy named Jurion before.(￣∇￣")
If the plot twist is like that, it means we have all been fooled by his innocent face.T__T
He also appeared in 327 (I think) in which duke met the black-masked dude (jurion who was hiding his identity, if you look carefully)
Okay thanks, I will reread that chapter ^^
Honestly, I'm also curious who gave that dangerous drug to Duke.,and of course I am also grateful to that strange person, if he had not given the medicine to Duke he would not have disappeared.But if the masked person is not gone I'm afraid he will cause even more serious problems, for example "Maybe later he will also give the medicine to Jiwoo's closest people (example: his close friends)" maybe ╮(￣▽￣)╭
