Arthur was silent for a long time before he nodded."She ... Did it on purpose. I knew it when she came down from the plane in America, but ... I never thought that she would change everything about me."
Arthur didn't approach qingsi immediately. Instead, he asked someone to follow her and report her daily movements and activities to him.
After a period of time, he became interested in Yan qingsi and decided to follow her. As he followed her ... He fell into her trap. Hence, he found an opportunity and saved her when she was being hunted down.
Thus, Yan qingsi and Arthur's friendship officially began. In the three years they were in country M, he was Yan qingsi's only friend. He was also someone she had always thought of as very important.
But ...
Arthur did not know if qingsi would never forgive him if she found out that even this friendship was his deliberate scheme.
