Lmao @ the comments below. did y’all even read/watch yona of the dawn? She realized that even though she doesn’t romantically love Suwon anymore, she can still care about him - because the trio grew up together and his betrayal is traumatizing and continues to influence her character development. And thus, she is growing up and becoming cooler every chapter
The author doesn’t make Suwon to be a literal demon king who’s cartoonishly evil. Yes, it’s possible to have gray area with your antagonists.
And yes I love yona of the dawn. This story seems to have promise as well.
