Intro. They are brothers. There is a legend that if someone has red eyes it will bring good fortune and power to that person. But no woman or man has ever had red eyes because it is either impossible or non-existent. But the four princes continued to search for someone with red eyes to marry and be their wife, but no woman had ever had a red star. But they still hope they will meet one day.
