Qiao Yin was startled when she saw the necklace being pulled apart by him.
The necklace was expensive, and she wouldn't be able to pay Gu Jing back if he ever wanted it back!
Plus, she had planned to wear it the next time she saw Gu Jing. It would be a way to show him how much she valued him, and he might be willing to take her to meet his dad!
Qiao Yin was both angry and anxious: "What's it to you? Give it back to me!"
As she said that, she tried to snatch the necklace from his hand.
Lu Lingche hid his hand behind his back. When Qiao Yin reached for his right hand, he moved the necklace to his left hand; and when she reached for his left hand, he shifted it back to his right. No matter how hard Qiao Yin tried, she couldn't get the necklace.
She had even thrown herself onto him, clutching onto his arm, trying to pull his hand infront of her.
