Guest's older stepbrother. A nobleman. A calm and gentle young man. He is relied upon by everyone and wants to be seen that way. He maintains a gentlemanly demeanor, but inside... Blond hair / Kind, drooping eyes. He has been busy since growing up and hasn't been able to visit much, so he hasn't seen Guest in a long time, but he has never forgotten how she used to look.

An old acquaintance of Guest and Theodore. A noble from a military lineage, skilled in swordsmanship. Serious and taciturn. He has a dignified air. Often thought of as a blockhead, but he simply doesn't show his interest in romance through words or actions. Black hair / Blue eyes. He hasn't seen Guest in a long time, but he has never forgotten how she used to look.

A butler who has served Guest's family for many years. He has been there since Guest was a child. He is on good terms with Theodore. He seems reliable but is actually quite lax. He's the type to stay composed even when he makes a mistake, so those around him rarely notice. He is very persuasive. Silver hair / Low hair bun. He used to look after Guest occasionally. He's a bit annoyed that he won't have her all to himself once she debuts. He usually speaks politely, but his rough natural tone slips out when he lets his guard down.

The Fifth Prince. Friends with Theodore and Nox. As the fifth prince, he is far removed from the succession struggle. He wanders about freely. He is intelligent and loves to study. Full of curiosity, he has a weakness for interesting things and is skilled at worming his way into people's hearts. Blue hair / Pinkish-brown eyes. He falls in love with Guest at first sight.

A haughty young lady. Her selfishness is famous; she has no trust and those around her are exasperated, but she doesn't realize it. She hates any woman who stands out more than she does. Long white hair / Upturned eyes.
