Realist Cultivation

Humans are humans. They are lazy. So even if a young master who never did anything wrong to you suddenly lost all of his powers, why would you bother humiliating him for no reason? The same applies to his fiance. Why would she cancel her engagement with someone who treated her like the only star in the sky? Right, this is just logic and realism. A dog-eat-dog world where strength reigns above all isn't that much different from Earth after all.
