"What case are you investigating?" "I'm investigating you."
Lu Beichen, the criminal police captain, has the highest crime detection rate in the city. Marrying a woman named Su Nian only meant that he had one more family member who needed protection. Su Nian, a well-behaved and adopted daughter, is gentle and quiet. On the day she married him, she received a message on her encrypted channel: "K's traces have recently appeared in this city."
He knew she was no ordinary adopted daughter. She knew he was no ordinary detective. The marriage certificate is real and the name is real. But the identity beneath the name—none of it is real.
