Li Shuang just did not like to break down in front of anyone. Having lost her parents at a young age and growing up with her grandpa, she just created a strong exterior for herself which did not allow her to shed tears in front of anyone. She was the type of person who would thrust her face in the pillow and cry her heart out till she got over the grievances of the whole day. It was her defense mechanism.
Mu Shen was not sure how he could understand her so well and he did not know why he wanted to know more, why he wanted to know everything about her. But he did not seek for an answer to that. Some things are better when left unknown.
He knew he should have stepped back, putting a proper distance between them. He knew that he should not have raised his hand to cup her cheeks but that's exactly what he did. There was still time to back off. He could have said that there was something on her face but he didn't.
