Wow, this is slightly more complex than I was expecting for a "banishment" manga

The eyes. I'm suspecting Haru and the hero are either descended from dragons or are dragons who don't remember what they are.

Stop being biased against the hero.
Isn't Haru to blame too? Calls himself a childhood friend but obviously fails to see his beloved friend changing. He is also partially at fault.
He keeps on going about how she changed and is a bitch to him while never thinking why she became like that.
Well he is pretty dumb so idk.

I was thinking about that, too. Her change seemed to be about protectiveness gone too far, but I wondered what event or series of events caused her to go from being protective to being yandere about it. Even to Haru it apparently was sudden and surprised him.
