Full of worry and guilt, Xing Tanxing stood rooted in the visitor's courtyard entrance. From her spot, she can see Rui's lonely back while he is looking at a far distance. But he is not looking at anything in particular. And Xing Tanxing knows that he is still thinking about his confession and rejection from Lin Xulian. She knows because she unintentionally heard everything when she was about to visit Lin Xulian.
Xing Tanxing felt really guilty because it was her idea for Rui to confess. And now he is in pain after being rejected. She is starting to doubt if her suggestions were right or was she just unnecessarily meddlesome. She cannot help but blame herself for Rui's current state.
