My Whole Family Are Villain

Don't understand why it's so popular.

There's a ml having ulterior motives towards a minor fl. And in stories like these, where siblings or twins are involved, the brother basically is non-existent. (why!! Even the dad treats him badly!) 

And the story is also nothing special. You'd think she would start some plans or something to protect her father but no. And why do they get unrealistically op in the later chapters?
