If one were intent on paying attention to the Crown Prince's affairs, they would discover them even more quickly.
The Crown Prince set down his teacup, bowed his head and pondered for a while, then asked, "Fourth Master, what benefits do you gain by telling me this? Or rather, why do you wish to tell me?"
Fourth Master smiled softly and said quietly, "No benefits. Your humble brother..."
He smiled again, with a hint of self-mockery, "Does the Crown Prince know that on this trip to Mongolia, your humble brother brought only one concubine?"
The Crown Prince looked at him and nodded.
"Your humble brother cherishes her, that's why he brought only her." Fourth Master looked at the Crown Prince, "The one whom the Crown Prince nurtures must also be someone you like, cherish. Your humble brother merely wishes to say, he understands such feelings."
The Crown Prince watched him, and after a long pause, let out a laugh.
