After entering Tao Zixin's house, she saw Tao Zixin's round eyes and smiled sweetly at herself. Tao Xiannuo It turned out that Tao Xiannuo's cold eyes became more tender. After Tao Xiannuo got to know Tao Zixin, his smile became more intense. After getting along with Tao Zixin, he came up with the idea of protecting her. Tao Xiannuo liked to raise his big hand and gently stroke Tao Zixin's hair, and said in his gentle voice, "Xinxin, I will stay with you forever." Whenever she heard this sentence, Tao Zixin would feel warm in her heart, and Tao Zixin was happy. Huan pulled Tao Xiannuo to play games, but there was never enough for Tao Xiannuo every time. Tao Xiannuo would deliberately let Tao Xiannuo slow down when Tao Zixin fell far behind him, waiting for her to catch up with him. On the first day they met, they agreed to draw a portrait of each other every year. When they grew up, they had this portrait as a souvenir. Tao Zixin called Tao Xiannuo to be Brother Nuo until she grew up. When she grew up, Tao Xiannuo asked Tao Zixin to change her name to Xiannuo. Tao Zixin obediently changed her name to Xiannuo. When Tao Zixin called Shu Xiannuo, another stage was reached. Tao Xiannuo asked Tao Zixin again. Zixin changed her name and called herself Arnold. Tao Zixin felt miserable, but she changed her name to Arnold obediently. Tao Xiannuo had always called Tao Zixin "Xinxin", so he didn't have to change his name like Tao Zixin.
