Xuenai felt that Cheng Rui was always far away from her and then close to her. When she was closer to him, he suddenly walked away again, leaving her alone to be friendly with whoever she wanted. When she finally knew that he couldn't love her because he was her brother, her half-brother, and she decided to hide her feelings and stay away from him, he came back and stayed with her, accompanying her to Dali, Yunnan, to Lijiang to climb the Jade Dragon Snow Mountain, to the places she once wanted to go, and then told her to give him a chance to love her. She was confused. She was 16 years old when she first met him. Now 10 years later, she could not understand him more and more.
