Xu Qiutong read a passage from nowhere, "The way you interact with a stranger the first few times will often become the lifelong pattern of the relationship between the two. For example, if you marry a person and you wash the dishes in the first month, nine times out of ten, you will wash the dishes for this person for the rest of your life. Or if you quarrel with a person, you admit your mistake first the first few times. Nine times out of ten, all future quarrels between you will end with you admitting your mistake." Xu Qiutong confessed at the age of 11. It has been 19 years since I met Ning Boyuan. In the beginning, Ning Boyuan helped Xu Qiutong. Xu Qiutong, who was bullied, found a supporter and followed Ning Boyuan loyally. Ning Boyuan did not push him. Although he opened her eyes, he didn't get closer to her. Xu Qiutong felt that it was good to be able to maintain such a casual friendship as classmates, even if he would never become Ning Boyuan's valued friend in his lifetime.
