Doctor's Pet in the Golden Age: the Princess Was Spoiled by the Regent

Once she traveled through time, she became the concubine of the Hou Mansion who was marrying in place of her elder sister, the crippled regent who held great power. It was rumored that he was violent and murderous. Even the current emperor was afraid of him. Everyone thought that she would not survive that night... A few months later, the secret guard came to report, "Your Majesty, the Princess has injured His Royal Highness the Crown Prince." "Your Majesty, the Emperor's beloved concubine was pushed into the water by the Princess." Facing the secret guard's report, the regent just replied with a simple reply: "The prince must have done something to anger the princess. Are you one by one? In the future, the princess will do this kind of teaching?" All the secret guards were in tears. Prince Regent, you have almost spoiled the princess.
