The Love-Urging Curse comes in two forms, Yin and Yang, planted in a man's and a woman's body respectively. When Yin and Yang merge, the two curses join, and the curse is lifted.
A Yao is beautiful and gentle, and she is due to marry her fiance in a month's time.
Everyone calls them a perfect couple.
Unexpectedly, an accident reveals that she and her younger brother-in-law have both been afflicted by the Love-Urging Curse.
The curse is ancient and mysterious, with few records about it. All people know is one line.
Thinking of that line, A Yao rolled her eyes at her frivolous younger brother-in-law.
She and her younger brother-in-law had studied under the same master, and had known each other longer than she had known her fiance.
But they had never gotten along. Other people saw A Yao as gentle, while her brother-in-law thought she had a bad temper.
She couldn't stand his carefree, unserious ways, and he thought she was affected and pretentious.
A Yao: "Is there really no other way to break this curse?"
Her younger brother-in-law's spirit pet flapped its wings. "One of you dies."
A Yao smiled at her brother-in-law. "Good idea."
The first time the Love-Urging Curse flared up, A Yao passed out from trying to endure it.
Her younger brother-in-law sat beside her for a quarter of an hour, watching her face grow paler, her body grow colder, and her consciousness fade.
At last, he sighed. "Sister-in-law, forgive me."
Then he kissed her moist, red lips.
He told himself, Just pretend I'm kissing a pig!
When A Yao woke up and saw her younger brother-in-law pressed against her lips, she punched him.
After that, every flare-up of the Love-Urging Curse was different.
Sometimes, her skin would grow hot, and the other person had to soothe her by touching her.
Sometimes, she felt as if she had fallen into an icy pool, and the warmth of the other person's tongue was needed to drive away the cold.
This can't go on. She is getting married in a month, and she has to find a solution before then!
