The little prince whose country was destroyed was saved by a theist. After that, he just wanted to give everything he had to the gods. What he just succeeded to the throne wanted was freedom.
When they met for the first time, he became a trainee knight, and he was already a noble prince; when they met for the second time, he became the prince's personal knight, caring for the smallest detail for the future of the planet; when they met for the third time, they became strangers, tit-for-tat but still did not forget their old feelings; for the fourth time, they parted and died, and their lives hung on a thread...
In this unspecified future, under the brilliant starry sky, even though they are riddled with wounds and have a tragic ending, they still help each other...
PS: Please forgive me for the short words...
Purpose: Just want to have fun
