What does she have ?

Ji Yu stayed with the Emperor for a few more minutes before she left his study, when she was with Zhai Tianyu, her lips were curled into a smile but the second she stepped out of the study, that smile fell ever so swiftly. Xiaolin who noticed that her mistress looked rather upset hurriedly chased after her as the two of them left the courtyard together. 

" What's the matter, missy?" asked Xiaolin as she looked at her mistress who was frowning, her face was taut and she was even biting her lips. This only happened when her missy was rather upset! " Did his majesty say something to you?" 

" No," Ji Yu shook her head as she replied to Xiaolin. " His majesty was ever so kind to me, he even prepared tea and cakes for me."
