Little sister Yeyue is just a weak girl who adores her big brother. Why did she slap a wild boar to death? Don't worry about it.

Big brother Yunyan is just a crybaby who dotes on his little sister. Why was he crying to her one moment, then staring coldly at his teammates the next?

...You know too much.

The family includes a mysterious mother who practices magic and cultivates immortality, a doting aunt who got tricked by her sister into becoming a free babysitter, a brother whose voice catches in his throat whenever he sees his sister, a little sister who's sunshine on the surface, and a dad who's a mysterious Demon King Michael Jackson (?)...

The whole family met on a message board.

Yeyue and her big brother Yunyan have lived with their mother for as long as they can remember. Their mother taught them all sorts of magical arts, like fortune-telling, summoning wind and rain, and the yin-yang eyes. And things like math problems. But their mother never let them use those arts outside of practice, and they weren't allowed to go down the mountain.

So aside from their mother and aunt, they'd never met anyone else.

That's right, they don't even know who their biological father is.

Yeyue points to the words in a book. “Mom, what is a dad?”

“It's a pig, an idiot, a joke, and lunch.”

After they grow up and meet their dad, the siblings say, “Our dad really is a pig, an idiot, and a joke!”

Why isn't he lunch? They were hungry, so they ate him. Ask no more.
