"Did his attitude towards you from when he first met you change, once you noticed he has started to do that?"
Xu Bao shook his head in negative.
His mother sighed in relief. "Good. Good. If it started that early, then it could be before he had met you. I don't think this has any bearings on your relationship with him.
I believe he might be doing something that he wants to keep a secret for now. There is no need for you to overthink this.
Just give him some time and see if he would tell you the truth himself. Or do you suspect that he might be involved in any criminal activities?"
"I don't know, Mama. I just hope that he isn't doing anything bad."
"Hmmm? Are you sure that you were not thinking of him seeing another may besides you?" His mama teased.
"I...I have go and lock the store room." Xu Bao shyly excused himself, he was getting embarrassed by his mother teasing him.
