"Yingying, hurry up and go out, you're not needed here," Li Yifei, in his attempt to prove his point once again, wrapped his arm around Xu Yingying's shoulder and pushed her towards the door.
With a reflexive struggle, Xu Yingying glanced outside, then twisted her body and said, "Alright, I'm leaving, you tend to your things." Then she quickly walked out.
Xu Yingying's reaction once again confirmed Li Yifei's speculation: she didn't like him and didn't truly want to be with him.
Since Xu Yingying didn't truly harbor affection for him, Li Yifei easily discerned her purpose—her actions were still about Xu Shanshan. Because Xu Shanshan had taken a liking to him, Xu Yingying didn't want such a scenario to unfold. It wasn't that she thought Li Yifei wasn't good enough, but rather, having such a situation arise at home was just too awkward. First her boyfriend, then her sister's—there was no explaining it to the parents.
