He is Yan Huaishen, the all-powerful head of the Yan family. She is Gu Qing'an, a fallen heiress with nowhere to call home.
The world says Yan Huaishen dotes on Gu Qing'an like she's the most precious thing in the world.
Danger lurks all around her, and there's always some scoundrel trying to harm her. Luckily, one person is always there to protect her.
Oh, wait. She also has her adoptive brother and her best friend. Hmm? When you put it that way, maybe she doesn't need him after all!
The man: "What did you say?"
Gu Qing'an: "Kisses for my hubby!"
