Spoiled Sparrow

[Both partners are virgins + wife-chasing scenario + extreme tug-of-war + insane male lead + imprisonment]
[A money-grubbing, fake heiress] vs. [A crazy, mature man who's actually a true tycoon]
"I'm used to it."
"I keep it as a pet."
"I will not get married."
......
Five years ago, the real daughter of the Su family was found, but the adopted daughter, Su Ruanqing, who was used as a substitute, was cruelly abandoned on a snowy New Year's Eve.
Just as she was contemplating suicide in despair, Fu Chen appeared.
She thought she had grasped a lifeline, but little did she know it was the next abyss.
He gave her cars, houses, and money—whatever she wanted—but he couldn't give her a legitimate status.
Fu Chen was confident that Ruan Qing would never escape his control.
Fu Chen went completely insane when the man who claimed to be his brother tried to take Ruan Qing away.
-
He imprisoned her in the castle, becoming so sickly that he could only fall asleep after feeling her body temperature all night...
Ruan Qing: "Fu Chen, are you crazy?"
Fu Chen: "You're too naive. Didn't you call me 'brother' too? Now you're climbing into my bed too!"
That night, his self-esteem and pride were shattered.
"Please listen to me, I'm begging you..."
-
On his wedding day, he was overjoyed, but what he received was a farewell letter.
"Fu Chen, I'm not serving you anymore."
