Yeah, now Seungho wouldn't believe him, but if NK had said the truth when he asked him what happened, he would've believed him. It's true the other two are also dangerous, but Seungho is more powerful (in the sense that he has a higher social status than the other dude) and is also crazy so he would crush him in two seconds and the bearded guy is just a mercenary, if you pay him more he'll come to your side.
Isn't it easier to just tell the truth? I'd be one billion times more scared of Seungho than the friendzoned-noble man and his killer
