Team Dowun all the way, but also yay for Lyon rejecting his hand even with a few people watching. That was so satisfying. *chef's kiss*. He deserves that, and more.
An IRL Dowun I'd run away from in a heartbeat. But in fiction, and given compelling circumstances of politics and power play in a historical setting, I truly appreciate the character Dowun has had to have in order to survive.
Soft-hearted and noble people like Baekhan would be a joy to have as a partner, had Lyon been anyone else but royalty. But as they were at the start of the series, the rotten system would eat them both alive.
So while I will definitely not call Dowun a good person, I can't say he's an evil cartoony villain either. And that what makes him such an interesting character to follow.
