**Childhood sweethearts, a marriage pact out of nowhere; jealousy runs rampant, and the romance is bone-deep sweet.**
Mu Zhinuan, the cherished little ray of sunshine in a top-tier wealthy family, lives by the motto, “As long as Brother Chen is here, everything will be fine.” Gu Yanchen, a cold and iron-fisted financial magnate, has just one weakness: the chattering little shadow at his heels. A drunken joke at a birthday banquet sends both families’ elders rushing to make a decision: childhood sweethearts? Then get married right now!
**A naïve bride, a relationship transformed:**
* When Mu Zhinuan puts on her wedding dress, she thinks she’s only changing locations to “stick close to Brother Chen.” It’s only after moving into his cold mansion that she discovers the vast difference between “brother” and “husband.” Her habitual “Brother Chen” earns her a low murmur as he bends toward her: “Get it wrong once, and you lose access to the master bedroom for a night.” When she sleepily crawls into his bed, she finds him staring at her with a look of restrained desire, his Adam’s apple bobbing.
* Gu Yanchen thought marrying her was the most hassle-free solution. He never expected his little wife’s colorful belongings to invade his territory, or that the sight of her childhood friend putting an arm around her and her many admirers showering her with attention would awaken the beast called possessiveness inside him. When did his “little sister” become someone else’s light?
**A jealous tycoon evolves in real time:**
* She wears the bracelet her second brother gave her? Mr. Gu takes off his watch right there. “Wear mine instead, or I’ll chop his hand off!”
* A male celebrity carries her on a variety show? The Gu Group’s official account immediately posts a childhood photo: “Her personal ride. Hands off!”
* He hears she’s staying over at her best friend’s place? He drives over in the middle of the night and knocks on the door. “Mrs. Gu can’t sleep in an unfamiliar bed. I’m taking her home!”
