Although Gu Dai had laid out the facts, Gu Ming still insisted, "You must have switched the necklace when we weren't paying attention. Gu Zhi is so pure and kind; she would never take your stuff!"
Unsurprised by Gu Ming's stubbornness, Gu Dai took out her phone and waved it, saying, "I have surveillance cameras installed at the entrance to the villa. If you're so convinced that I switched the necklace, feel free to check the footage."
Gu Zhi's face turned pale in an instant. She had adamantly denied taking the necklace, banking on the fact that Gu Dai had no proof. But now, it turned out Gu Dai had surveillance cameras.
After watching the surveillance footage multiple times, it became abundantly clear that Gu Dai hadn't switched the necklace. The one she held in her hand was indeed the one that Gu Zhi had given her.
