"He's mean to everyone else but me" trope

I FUCKING HATE IT! omg I don't understand how people can enjoy it, like sure you want the mc to be treated like their more special than everyone else for the ml but people genuinely write mls who neglect their own children because they're jealous mc pays attention to someone else other than them??? ITS DISTURBING. I've seen it a lot in straight romance and omegaverse like bruh why would i enjoy reading about a ml who abuses his own children
