Shen Yan didn't know what Gao Ya's identity was, she only knew that this was Ouyang Xiao's friend and was currently staying at her place. However, this woman had been constantly paying attention to the situation opposite her during her stay here, looking even more concerned about Tang Ming's every move than she was.
After failing to assassinate Tang Ming in the provincial capital, Gao Ya rushed to Songlan City to meet Ouyang Xiao. Seeing Ouyang Xiao's pitiful appearance further solidified her determination to kill Tang Ming. So, she proposed moving in with Shen Yan to make it easier for her to monitor Tang Ming and find the opportunity to assassinate him.
Ouyang Xiao hated Tang Ming deeply, so when Gao Ya suggested moving to Shen Yan's place, she did not object. It was just as well since she had a lot of work to do at the end of the year and had no time to accompany Gao Ya. Letting her stay with Shen Yan wouldn't be too boring.
"Are you a professional killer?"
