Yeah. I don't know what is happening in chapter 91 as I don't understand Korean but indeed he seems like a spoiled angry kitten.
He’s cranky his assassination plan didn’t work. The the ML essentially bent him over and called him his b*tch with none of the pleasure.

So he can keep an eye on him. Like, it’s clearly for plot purposes but damn
Not me thinking Master Silver hair was all cool and collected. Who knew he’d be an angry brat I love it.
