(A fierce and adorable female lead VS an obsessive and sinister male lead, sweet doting + metaphysics + slight fantasy)

Jiang Xiaoxiao, the great master of the Mystic Sect, was born with an incomplete soul. Every full moon night, she would also turn into a tiny three-inch tall person.

The Grand Master said that in the sixteenth year of her life, she would meet a nobleman. The purple gold dragon aura on the nobleman’s body could lift her curse.

Xie Xun, the King of Chu, had his dragon aura taken away at the age of three. Plagued by bad luck, he was exiled from the capital.

The first time he met his adorable wife, his adorable wife shrank with a swoosh in front of him into a tiny three-inch being, standing in his palm dozing off.

Later, the King of Chu sewed a small pouch on the sleeve of each garment. When going out, he would put his adorable wife in the pouch.

And he told others, “My little one is weak, pitiful, and helpless.”

The little ghost shivered in fear: Have you seen someone using a kitchen knife to hack ghosts at a mass grave? Yes, it’s your weak, pitiful and helpless Queen!

The ghosts wailed at the mass grave: Have you seen a living person who could scare the ghosts to tears? Yes, it’s still your weak, pitiful and helpless Queen!

The entire netherworld exploded: Have you seen a newly wedded bride escorted by two Ghost Emperors and two Ghost Kings? Yes, it’s still your weak, pitiful and helpless Queen!

When she stands, she’s like a white peony. When she sits, she’s like a tree peony. When she walks, she’s like a lily flower. And when you look her in the eyes, she’s like the Great King of Terror.

Despite having the qualities to be a peerless bishoujo, because of the look of her eyes and that atmosphere of hers, she’s feared by others; such a girl is forcefully sent to another world.

Being told that she would be granted a wish as a special favour, the girl made a wish────

“Make my eyes and atmosphere normal please.”

This is a story recounting the lifestyle in a parallel world of a girl who would be perfect (probably) if just her one weakpoint was overcome.

A fantasy comedy with magic, dungeons, and a hero and demon king(candidate) who she gets tangled up with.
