For Ding Fan, He Qianyao was not merely connected through He Zenfen, even though Ding Fan knew that He Qianyao's father, the former Dayang Sect Master He Zenfen, had saved his life. Thus, Ding Fan was entrusted by Sect Master He to take good care of He Qianyao.
To Ding Fan, his connection with He Qianyao had already surpassed that single layer of relationship. Clearly, Ding Fan could feel everything she did for him. However, Ding Fan found it hard to accommodate anyone else in his heart, since both Zhou Ruoran and Gusu Qingwen remained unfound.
This was the biggest concern for Ding Fan. Thus, while Ding Fan found it hard to accommodate anyone else, it didn't mean he was oblivious to He Qianyao's love for him.
Ding Fan had occasionally noticed the slightly jealous expressions she wore, and he could only change the subject, as this was somewhat awkward for him.
