Shao Rong was standing by the window looking outside with her eyes turned so cold that Sun Bingwen would not believe that she was really the Shao Rong whom he would call Sister Rong with so much respect and familiarity.
In front of him, she would not talk much like when she was in the act of Rong Rong, but still she would converge all her aura so that he would feel a little closer to her until the time they stay together. She doesn't want him to stay on his toes being nervous around her when he was living in his own house.
Though she can really order him around, she is not so unreasonable that she would boss around a man who is neither her subordinate nor a man who offended her. So she would give him the basic respect that he deserves. After looking at him for this period of time, she started liking him and wants to really treat him like her younger brother.
Hence started petting him and smiling at him so he could feel more comfortable.
Why do you guys think Sun Bingwen hyperventilated when he saw that Shao Rong's face was clean?
Any guesses?
