But the recorder has already been stolen.
"There's no sign of the car lock being tampered with; the person who stole the surveillance recorder should have a car key. Besides me, only Yan Gang and the company's driver have keys to that Mercedes. The driver is on leave for the past couple of days and went back to his hometown, so the only one who could enter the car and take the recorder now is Yan Gang."
Considering Yan Gang's character, it's naturally impossible for him to steal the surveillance recorder; he has no reason to do so.
So, there's only one possibility—Tang Ru stole his car keys and took the surveillance recorder while he wasn't paying attention.
But there's another issue here—
"Considering Yan Gang's understanding of Tang Ru, she shouldn't have such sophisticated means or think of so many tricks."
