@cinic Not every character needs development. Some characters exist as foils or as relief. Baek Han doesn't necessarily need to develop because he's a saint, but we might see him tread down a dark path (I doubt it). I don't think Baek Han is badly written. He doesn't exist solely as plot device or to stir drama. He has his own set of circumstances/issues, his motivations/convictions, and his dilemmas. I don't consider him one dimensional either. Also, you can't really expect people to give him a horse in the race when he didn't have much screen time. He was literally a prisoner on death row, lol.
I think Dowun is more interesting than Baek Han, and I love Dowun more than Baek Han, but Baek Han is the one I ship with Hong Lyon.
