NGL he grows on you and seeing the story behind his servant really makes you understand why he was so resentful. Now he doesn't know what to do with those feelings since Haru is back.
To be fair I disliked him at first because what he did was really reckless and sort of a "If I can't be happy/can't be with Nagi then no one else can" but in the end he did give Yua his own blessing during the ritual.
Oh God I thought I'd be the only one because there's a lot of people commenting how much they dislike hao but you spoke the truth. Yes, we do get an understanding as to why he was the way he was with kotone, nagi & with his servant in the beginning.
I disliked him too because he was being nosey & too obsessed. But, after reading his story & seeing what had happened; I understood. I never hated him & I actually hope to get more of his story.
Honestly Hao has been through quite a lot if you put things into perspective.
1. His lover/sibling/counterpart got torn away from him because another divine beast abandoned his duties
2. His servant took a long time to come (Nagi too definitely)
3. His servant went back to make amends and was whisked away by some troublemaker for 200 years, of which Hao had assumed that he never wanted to return.
Like that man had everyone he was close to stripped away from him and people hate him because he tried to bind Nagi to him again? He showed what he was made of when he wanted to rescue his servant. (Plus it was a sore spot that Wu touched when Hao didn't get what he wanted with Nagi, but in the end it did work out and Nagi became a divine beast )
I know a lot of people dislike hao because of his tsundere & stubborn personality but I like reading his story. Tbh I wanna know his & his servant's story just like I like to know all of the sacred beasts stories. I feel like we get a lot of kotone & nagi's story that getting a new one of another couple is kinda refreshing if that makes sense. Don't get me wrong I love reading some kotonagi along with their baby but I like reading a new couple for a change. Also I do hope we get new babies from the other sacred beasts because it's needed.
