After rebirth, I made the princes cry

Introduction: Since Wang Yingshu entered the palace, many people felt that something was wrong. Queen: Why do I still need to learn moral standards when I already have a mother who respects the world? All the harems: Why do we have to compete with each other to see who loves the emperor most sincerely? The prince who has always relied on fighting for his father to win: Why do you suddenly feel that I have no father? A prince who can obviously compete with his grandfather: why should he become a top student first in order to win the crown prince? The little prince who doesn't want to be the emperor at all: Father, my mother said that Wang's daughter is causing trouble in the palace and is a disaster. Emperor: Your mother is uneducated. She is a female minister, a court official, and your future sister-in-law. Little Prince: Who is your sister-in-law? Emperor: That depends on which of your brothers is the most capable. certain
