[Wicked wife + space + adorable child + chief minister + building wealth + heroine starts out dark and turns good + male lead starts out good and turns dark]
Shen Changge, an ugly, overweight matchmaker who loved money and handsome men, was always looking for a way to divorce her disabled live-in husband.
He cooked, and Shen Changge said, “Wow, that smells great! Your pig slop turned out so well!”
He wrote, and Shen Changge said, “Wow, that's amazing! You can even write with your feet!”
He handed over his monthly allowance, and Shen Changge said, “Wow, that's a lot! Even the ants at your house couldn't carry it all!”
He became chief minister, and Shen Changge said, “Wow, what a high office! I bet even the village head's big yellow dog would kneel when it saw you!”
“You don't want to?”
“Then we're not right for each other. Let's divorce!”
“What?”
“You won't divorce me?”
“And the emperor wants to arrange a marriage for us?”
Shen Changge burst into tears. “Waaah... I only wanted to divorce my husband. Why is that so hard?”
