This plot comes from Zhang Ailing's novel Lust, Caution. Mr. yi insisted that the ring was not his, because he thought it was given to Wang Jiayi by him and had nothing to do with him. Besides, she wanted to keep this secret, and didn't want anyone to know that this precious diamond ring was given to her by herself. In front of Japanese eyeliner, Yi Jianlian's private life is almost nowhere to hide, so he is unwilling to disclose any information about the ring.

At the same time, he also realized that if his relationship with Wang Jiayi was known, it might have a negative impact on his political status. In mr. yi's mind, his feelings for Wang Jiayi are profound, but he doesn't want to make this relationship public, so as not to cause unnecessary doubts and troubles. Therefore, he chose to deny that the ring belonged to him to protect their relationship from being discovered.
