In order to find the ring Mochi mentioned. Yuni can't avoid physical contact with Prince of Ye. He took the advantage and kissed her. At the same time, Prince of Ye found that the Grand Councilor was cheating on the Emperor and the true identity of Yunxi.
Seems he isn't who Mochi's after. 
I should clear out now.
يبدو أنّه ليس من يستهدفه موتشي. ينبغي
أن أنصرف الآن
Non è lui che Mochi sta cercando. 
Posso andare.
Parece que não é ele
que o Mochi procura.
Теперь я уверена, что Мочи ошибся.
