I have mixed feelings about Dowun because part of me still hopes that he can grow emotionally and realize he needed to show more love and vulnerability towards her if he were to ever win her heart. However, I don't know if he even loves her or not. I'm not surprised she has hardened her heart against him. I'd be wary once there's an heir and he technically won't need her to rule anymore. I just want our poor girl to have some warmth in her life. Unfortunately, it looks like only the bodyguard can give her that. He seems the most genuine.
