You want me to kiss you?

The Crown Prince demanded fulfillment of a wish which Ying Lili would not have thought of even in her dreams. How could she think that the Crown Prince would ask for something like that when their affection towards each other had not even grown a bit?

"Sheng Li, if you had asked me to be a spy I would have agreed with you. Why did you ask this as a wish?" Ying Lili confusedly asked. 

"I have not completed my words. You would have stepped back once you will know where we actually need to go," Sheng Li affirmed and asked, "Have you ever done spying?"
