I feel like people are really going overboard? Sure, I agree the red dragon should've been nicer and not kill the family and all but keeping in mind his personality, it would've made no sense for him to not kill her family, plus, if Mir didn't get to live in the palace from such a young age she wouldn't have developed the desire to kill the emperor and all her revenge.
I get y'all being angry at the emperor and empress but they literally just strike me as a couple of partners in crime that really just want the same thing. Emperor wants to die because he is tired of the pain and of living eternally and saw his race get extinguished. Empress feels pity for the Emperor and wants him to die to find his peace as he did with her, or that id what I'm getting so far.
I also think the Emperor killed Lady Yurian (Knight) because he thought Mir was going to be happy to see the one who killed her dead. Of course, I'm not saying this excuses his behaviour, but it explains what he is thinking, for example, he was really surprised when Mir tried to kill him after he killed her family, he was not expecting her to be angry about it, or at least angry in a way of "You killed my family", he must've been expecting something amongst the lines of "You killed my prey, therefore you stepped on my pride and deserve to die". I feel like the red dragon believed if he let the family live, MC would become close to them and forgive them, which is why he chose to kill the family, not really expecting MC to be so close to them yet.
Y'all are also on-board with the BlondiexMir ship and I can totally tell Klaus is going to be such a bad person that will make us forgive the red dragon one way or another, you all hate the empress and emperor for their schemes? Please don't lie and say you haven't deduced blondie has a friking big scheme in his hand and our MC is just a puppet to him.
I don't ship any of the guys with the MC because I feel she is too pure and just wants to have familial and platonic love in her life, but yeah, off you go with your ships, I support as long as you don't curse somebody else for shipping something you don't approve of.
