Well, it so happened that the second generation of "Heavenly Primates" was formed according to the plot, but of course we will not say that two of them are demons, no no.
Absolutely everyone has their own second "prototype", which is their opposite.
The monkey King is someone who used to always act as he wanted, he made many mistakes for which he only began to feel ashamed after many years. More often than not, he did everything in his favor regardless of others.
Xiang is not, he was benevolent from the very beginning, helping others without expecting at least some kind of reward.
Probably one of the main qualities that could show similarities between these two is envy. Macaque was jealous of Wukong, envious of how much he loved him, how much they admired him, and this was the reason for his downfall. And it would seem that Meilin should also feel envy, envy of how Lan is praised and put in the first place, but no, and perhaps at first it was like that, in childhood, but as she grew older, she realized that instead of wanting to take someone else's place, she would find her own.
Hou is someone who has found his strength in fire, steel, war, he is a warrior whose poise can sometimes surprise, to see him in anger is equivalent to finding the end of the rainbow. Meanwhile, Lan, whose rage knows no bounds and destroys everything in its path.
And this duet is truly amazing. Riluo is cunning, he knows how to plot, keep secrets that will be forgotten... Empathy? He doesn't know the word, he'll smile just for the sake of decency. Xue, oh, this little ray of sunshine, her heart and soul are pure, she will always be sincere with you, and will try to help, no matter the physical or mental pain.
