Xiao Sheng had been dealing with various people since he was young. Coupled with the fact that Duan Mei had gone to the village to cause trouble last time and Yu Bing's decision to stay in the guest house instead of going home this time, he knew that Yu Bing's relationship with her family wasn't good.
The first thing Yu Pan and Yu Bing talked about just now showed how badly the Yu family treated Yu Bing, so Xiao Sheng tactfully didn't interrupt.
After all, not many sisters would criticize their sister whom they hadn't seen for a year the moment they saw each other again.
She even implied that Yu Bing was promiscuous. Moreover, she didn't care about Yu Bing's reputation at all and insulted her in public.
Xiao Sheng was worried that Yu Bing was in a bad mood, so he racked his brain to find a topic to talk about, in hopes of diverting her attention.
