It wasn't Xia Ziqian's introverted nature that made him dislike her, but rather an unpleasant encounter they had.
Even though he was young, he was popular among all the girls, regardless of their grade level. Many girls would come to see him, and although Xia Ziqian didn't care, it did inflate his ego a bit.
But this short-lived arrogance was completely destroyed by a little girl named Xiaoshan.
Sometimes, Xia Ziqian would struggle in his crafts class. He disliked doing hands-on work as well as turning junk into treasure. However, Xiaoshan was incredibly good at it. Anything that ended up in her hands would be transformed into something beautiful and useful. So, the crafts teacher asked Xiaoshan to help Xia Ziqian.
But before Xia Ziqian could refuse, Xiaoshan said in front of the whole class: "I don't help people who aren't dedicated."
Then she outright rejected the teacher's suggestion.
