After Mistaking the Villain for My Future Husband and Raising Him

As soon as A Fu takes human form, her mother tells her to pick a youngling to be her child-bridegroom.

A Fu doesn't know what a child-bridegroom is. Her mother says it's someone who will stay with her for her whole life. After careful thought, she immediately picks the plumpest youngling.

A little fat is good. It makes you tougher. Her father quietly told her that.

A Fu would never dream of hitting her youngling. His fur is the smoothest, and he's the cutest, though he is a little picky about food.

But that's all right. He's the youngling she picked, so she'll spoil him!

A Fu gives him the best fruit, grooms his feathers every day, and looks forward to marrying him after he takes human form.

Mu Yuan is knocked back into his original form during the war between the immortals and demons. He loses all his magic and is forcibly taken away by a chubby little girl.

The chubby little girl feeds him wild fruit he doesn't like and makes him get his fur combed every day. She even cuddles him while they sleep.

He thinks: This is a disgrace beyond all measure. Once I recover, I'll kill her!

The Demon King goes missing, and the demon realm falls into chaos.

Mu Yuan's subordinates search everywhere for their boss. Then, on a small island, they see their cold and merciless Demon King in his original form, rolling around in front of a little demon with his dark belly exposed, begging her to pet him.

"You little enchantress, what bewitching spell did you cast on our Demon King?"

A Fu: ...What's a bewitching spell?

Mu Yuan: I don't know either.

Theme: Love yourself.
