An Jing had long been acquainted with Bai Qinghan.
The reason was rather amusing: like many other children, Bai Qinghan had never learned to read, she was illiterate, which made it difficult for her to learn Martial Skills and comprehend the Imperial Heaven Scripture.
An Jing worried about this to no end, even going so far as to use his personal time to tutor these little illiterates privately, helping them to learn characters and Martial Skills as quickly as possible.
Bai Qinghan was one of the quickest learners among them, often singled out for praise by An Jing as a model student to be commended.
At that time, he and Bai Qinghan had formed an impression of each other, but they barely spoke, even when An Jing praised her, Bai Qinghan would just hum softly, appearing very shy.
As for their formal acquaintance, it stemmed from a sparring session.
