"I don't know. She didn't tell anyone. She just left like that. Mr. Nangong only knows she went to pay respects to her mother, but we all know that's not true; it's just an excuse," Chu Molin listened to Qin Xue talk about Nangong Beiying's past, so he knows Nangong Beiying wouldn't really go to pay respects to her mother. According to Qin Xue, her mother passed away in the Imperial Capital, and the grave is here, so there's no need to go anywhere else.
The only explanation is she didn't want to face everything here, so she left. With this thought, Chu Molin looked at Xiao Qi with some suspicion.
"Boss, why are you looking at me like that? I don't know she left. Otherwise, I wouldn't be looking for her everywhere," Xiao Qi thought Chu Molin was suspecting him of knowing Nangong Beiying left and pretending not to know.
