Looking at this photo of Bogum, for some reason I think he'd suit a tyrant role well too lol.

For some reason, the cold and sharp look from "Remember You" also comes to mind.

Your cold appearance is impressive.

Hanbok also in striking white and black

It catches my eye even more because of the fluttering pattern.

I had a thought that he might also do a good job playing a slightly creepy tyrant...?
