Nowhere to Run! My Enemy's Unhinged Younger Brother Falls for Me

[Modern Romance + Wealthy CEO + Sweet Romance + Forced Marriage and Ruthless Pursuit + Powerful Leads + Unhinged + Cunning + Both Leads Devoted + Happy Ending] [Cunning, Clumsy Beauty × “Unhinged” Mysterious Undercover Agent] The biggest regret of Su You'en's life was taking one extra look at Bai Gang's richest man, Gu Yunqi, at her best friend's wedding. That suited-up devil abducted the bride in front of everyone, then shoved Su You'en, the maid of honor, into an exploding car! When she opened her eyes again, she had become the “crazy woman” in a psychiatric hospital. And the one assigned to supervise her was none other than Gu Yunqi's ascetic, “unhinged” younger brother, Gu Yunzhou! Gu Yunzhou gripped her chin and sneered. “Run again, and I'll put you in shackles myself.” Later, she discovered that he was actually a sweet, innocent little puppy on a police mission. And that self-controlled lunatic who said, “You can touch me only after we're married,” drugged her milk on the night he proposed... “Gu Yunzhou, are you here to save me or sleep with me, damn it?” He bit her earlobe and panted softly. “Both.” * He's an illegitimate son of a wealthy family, and she's a rich heiress seeking revenge. One likes to pretend to be crazy, the other likes to play dumb. In reality, one is an exceptionally capable undercover special forces soldier, and the other is a quick-witted performer with exceptional brains and brawn. A fighting couple: cross them at your own risk.
