Fang Mo was there only to deliver the document; he was needed back at work in the afternoon, so he left after lunch. Mother Ye and Father Ye were both elders, and they weren't close to Fang Mo, so naturally, the task of sending him off landed on Ye Shuang's shoulders.
On the way to Fang Mo's car, it would have been too awkward for the two of them to not chat. However, even though Ye Shuang had worked under Fang Mo for quite a long period of time, her former posting at work hadn't brought her into close contact to the big boss, so their own shared topic was the male Ye Shuang.
Fang Mo felt it was weird for a man and woman to have their conservation solely around the woman's boyfriend. If there was nothing wrong with this man, there could only be two possibilities; one, the man was interested in the woman; two, the man was interested in the woman's boyfriend. Neither of the possibilities was the impression Fang Mo was trying to make.
