How the FUCK could anyone think that story, that payoff, was anything but terrible. The king stole his daughter's memory, fine. But then the dead friend was fine, soooooo, return it you idiot. He instead watches his horrible daughter torture her sister for decades. And that bitch hypnotized her ENTIRE NATION. They're both super villains. Even all that would have been fine if the MC called them out on their bullshit and hypocrisy, but he smiles and tells the girl to go make up with her abusers. That's some Naruto level bad writing right there!
