Spoiling the Darling Sparrow

[Both leads are devoted to each other + the male lead chases his wife after losing her + intense push and pull + unhinged male lead + imprisonment] [Money-loving, pampered fake heiress] vs. [Unhinged, mature true heir to a wealthy family] “I’m used to it.” “I’m just keeping you around for fun.” “I’ll never get married.” Five years ago, the Su family found their biological daughter. On New Year’s Eve, they cruelly abandoned Su Ruanqing, the adopted daughter they had kept as a replacement. Just as she was about to give up and end her life, Fu Chen appeared. She thought she’d found a lifeline, but he turned out to be her next descent into hell. Cars, houses, money: he gave her whatever she wanted, except the right to stand openly by his side. Fu Chen was sure Ruanqing would never escape his control. Until the man who called himself her brother tried to take her away. Then Fu Chen completely lost his mind. - He locked her up in a castle, so sick with obsession that he could only sleep after feeling her warmth all night... Ruanqing: “Fu Chen, have you lost your mind?” Fu Chen: “You’re the naive one. Didn’t you call me your brother too? Now you’re in my bed all the same!” That night, his pride and self-respect shattered completely. “Please, be good. I’m begging you...” - On their wedding day, he was full of joy. Instead, the only thing waiting for him was a farewell letter. “Fu Chen, I’m done putting up with you.”
