Little Rabbit A Nian

Also known as The Demon King, You're in Trouble! You've Fallen in Love!

The goddess Jinnian gave her life for the Dao to secure a place for demons to live in the Six Realms, blessing the world in the process.

The demon king Chu Huaiqin had always been arrogant and free-spirited. But after the goddess fell, life suddenly seemed dull and tasteless, so he simply split open a mountain cave and went into seclusion.

A hundred years after the goddess fell, the demon king had been in seclusion for a hundred years.

A-Nian was a rabbit born and raised on Hu Mountain. All she knew was eating grass and digging burrows, until one day she met a handsome immortal in a blue-green robe. He affectionately called her Jinnian, awakened her intellect, and gave her a human form.

After that, she met Wu Sui, a demon cultivator who had also taken human form on Hu Mountain, though more than ten years before her. She accepted him as her big brother and followed him out into the human world.

But later, her big brother started acting strange. He was always getting angry, and the demon aura around him grew more and more domineering.
