I'm so confused why would he keep on going like he doesn't have blackmail after all that

The other dude still has the videos and is threatening MC w/ them

I mean why is bossman still abusing him when he knows he has the blackmail

Ooh, I think it’s because he thought he didn’t have it (blackmail) since he had taken his phone (but then he saw he still had the videos on his new one?). That or he kinda dumb
