There's a story just like this but with a dragon seme, what was it?
No, not that. It had a ml getting reborn and trying to avoid the dragon again due to his mistreatment of him: breaking of limbs, killing of people, alienating him. But in the end it came to be understood that it was a cultural and species difference of why he did what he did and didn't understand why it was wrong until the current life time.










So why didn't he kill the brother or previous crown prince?
