The Tyrant's Development Plan (Thread Book)

Yin Wanwan walked into a book. She became the vicious sister of the tyrant. According to the plot, in the future she will be crippled by a tyrant and marry an inhumane old man. When Yin Wanwan came through, she was leading a group of friends to punch and kick the tyrant who was still a pitiful little tyrant at this moment. Facing the tyrant's fierce and cold gaze, Yin Wanwan suddenly thought of her miserable fate in the future. She swallowed her saliva and stopped in front of the tyrant, "Brother, don't be afraid, I'm here to protect you." Yin Ziyun never thought that someone would stand in front of him and say that he would protect him. For the first time, there was light in his cold and dark eyes, like a ray of light coming in. He held her hand, his eyes as determined as a lone wolf's, "Are you telling the truth?" Yin Wanwan was a little confused but nodded seriously, "I will protect you from now on." She doesn't know what she promised? ———— Many years later, when Yin Wanwan was about to get married, Yin Ziyun held her in the palace and pressed her in front of the imperial palace. His voice was hoarse and he said, "Wanwan, you said you would never leave in the future." Yin Wanwan was about to cry but had no tears: "..." When did she say that?
