The Wealthy Heir I Married in a Flash Is Mentally Ill

[Mutual redemption + Older woman and younger man + Fake fool x genuinely mentally ill + Slow and steady]

Yu Qing has something wrong with her brain. When she learns she's impulsively married a mentally ill man, she isn't afraid at all. She's delighted.

Everyone says she's going to be a free nanny and punching bag.

The young master's destructive streak is so bad that his family has been driven to the brink of despair by him.

They're all waiting to see her make a fool of herself.

Instead, they see Yu Qing receive the castle and wedding of her dreams.

And a young, fit, obedient, wealthy, devoted guard dog who knows how to talk himself into things.

They also see Yu Qing, once a fool who'd been emotionally abused by her family for years, become a dazzling sun with a successful career, thanks to Mu Xu raising her himself.

One they can only look up to.

-

To Yu Qing, Mu Xu is the only lifeline pulling her out of a suffocating place. She can only cling to him, climb toward him, and desperately draw sustenance from him.

She wants to live, and to live happily.

Nothing else matters.

-

To Mu Xu, Yu Qing is the only sunlight willing to shine on him.

He uses a grand scheme to give her the life she wants.

For her, he tames himself into an obedient, good dog.

He willingly offers everything to his older sister.
