Ou Renjin likes keeping beautiful young men because he likes watching the drama.

Watching them be arrogant and conceited; watching them be obsequious and sycophantic; watching them have ulterior motives and fight with each other, seeing all the evil side of human nature.

…saying to him in the calmest and lightest of tones after knowing that their heart matching is successful, “I am very grateful that you have been hiding it from me, but I have long been ready to give my heart to you.”
