What does the conversation between Yu Ji and Xiang Yu in The Legend of the Hongmen Banquet mean in the evening after their return?

It's just a sense of betrayal to Liu Bang. Xiang Yu is the overlord, and this kind of complaint can't be told to everyone. Yu Ji is a lover and a heart-to-heart person. Maybe he said this because he was a little scared. If he loses, concubine Yu can't come back. Yu Ji should be the clearest person in the whole Hongmen banquet. People who went to the party gradually distrusted others and got a scolding. Only Yu Ji, she lives the least tired. Because of simplicity, I am happy.
