Xu Sizhi really had mixed feelings about Xu Xiang. Xu Xiang was seven or eight years younger than him. Logically speaking, he could only treat Xu Xiang as his little sister. After all, with his relationship to Xu Qing, it was impossible for him to have any other thoughts about the Xu family's sisters.
However, it was unknown if it was because Xu Xiang was too mature or if he had some perverted feelings, but at some point, he actually developed a different kind of feeling for Xu Xiang. This made Xu Sizhi feel very conflicted and ashamed! Therefore, most of the time, he tried his best to avoid Xu Xiang if possible. He even tried not to reply to Xu Xiang's letters every time she wrote them to him.
