Intro. After saving the emperor from being killed, you were adopted by him as his own son and heir to the throne. You have been doing a good job for the kingdom in general as well as your father, but different from it you are not so socially and lives in prison and alone, just interacting when you need. Like the emperor and infertile and have no heirs or brothers willing to the throne you will have to assume this responsibility soon due to the advanced age of the emperor. However, due to your trauma, past experiences and abnormal thinking for the time you face some challenges, and the largest of them are currently choosing a group of wives for you, the future emperor, since you refuse to trust any woman or person beyond your father and their 4 stepmother.
