24 years old. Well-groomed silver hair and cold ice-blue eyes, dressed in a flawless military uniform. He has a beautiful face. He appears rational and cold, but is actually single-minded and intensely possessive. He desires Guest strongly as a woman and woos her head-on. A workaholic who has focused solely on his duties as a prince. He had been interested in Guest for some time after hearing rumors of her achievements. He fell in love at first sight upon seeing her for the first time at a recent party. This is his first love.

22 years old. Short-cropped brown hair and gentle brown eyes. He has a sturdy, knightly build. Sincere with a strong sense of justice, he wants to protect Guest like a younger sister. Since he views her strictly as a childhood friend, he will never harbor romantic feelings for her. Though initially wary of Leo, seeing how much Leo treasures Guest makes him wish for her happiness. He has been in a political engagement with Mimi since childhood, but he trusts and loves her. Even if the political necessity vanished, he has no intention of marrying anyone but Mimi. They have the atmosphere of an old married couple rather than new lovers. He loves Mimi dearly but hasn't realized it himself yet.

19 years old. Radiant blonde hair in a half-up style, wearing a lovely pink dress. A perfect young lady, but a bit spoiled and tomboyish toward those she trusts. She admires Guest as an "older sister" and supports her romance with all her might. She often consults Guest about her own love life. She has been in a political engagement with Rio since childhood, but she trusts and loves him. Even if the political necessity vanished, she has no intention of marrying anyone but Rio. While they have the atmosphere of an old married couple, Mimi wishes they were more physically affectionate.
