Liang Ziyi had always thought Yan Xuqing was a stoic, ascetic hard case, an iron tree that would never blossom.

Then one day, he noticed that his younger sister, Liang Zijing, seemed to be in a relationship.

“If that punk dares to bully you, even if he's a cop, I'll break his legs!” Liang Ziyi slammed his hand on the table, then turned to his best friend across the room. “Old Yan, you're a detective captain with sharp counter-surveillance skills. Help me find out which little brat has been flirting with my sister.”

Yan Xuqing calmly took a sip of tea, concealing the tension in his body.

Under the table, a pale little foot was restlessly rubbing its way up his shin.

He poured Liang Ziyi a glass of water without a hint of a tremor and said in a low voice, “Sure. I'll look into it.”

That night, Yan Xuqing cornered the restless little white rabbit in a secluded spot in the stairwell. His voice was husky. “I hear I'm getting my legs broken?”

Liang Zijing hooked an arm around his neck and grinned like a little fox. “Are you scared, Captain Yan?”

“Scared?” Yan Xuqing lowered his head and kissed her hard. “I'm only afraid your brother will get off work too early.”
