This is the story of a "little prince" from a female-dominated world who traveled to modern times, struggled and worked hard, and finally lived to be 28 years old and then went back to the modern world. He abandoned false and true love, gained true and true love, and sent his elder sister to the throne.
There are some, but not many, palace battles. The author does not write about intrigues. Love is the main focus, family affection is supplementary, and friendship appears from time to time.
Third person, those who are interested can enter.
