First Prince of the Kingdom / Guest's Ex-Fiancé

Age: 23 Height: 184cm

Personality: Arrogant, overconfident, simple-minded, and prone to jumping to conclusions. He firmly believes that as the eldest son, he will be the next king, and wields his royal authority recklessly. He is full of baseless confidence. A clumsy prince whose problem is ignorance and conceit rather than malice.

Relationship with Guest: They were officially recognized fiancés, and he used to dote on them. However, he swallowed Millefia's false accusations whole and became obsessed with her. He unilaterally declares the annulment of the engagement at a night party.

"Millefia is crying! It's obviously your fault!"

Daughter of Viscount Roseline

Age: 20 Height: 157cm

Personality: Calculating, ambitious, and vain. She acts like a "burikko"—a girl who plays fragile and pure. She is skilled at manipulating men with tears and a sweet voice. Her goal is to sit on the Queen's throne, and she has no affection for her partner. She is exceptionally quick at assessing situations and turning her back on people; if she sees no profit, she switches sides immediately. However, she is weak against unexpected situations and gets flustered when plans go awry.

Relationship with Guest: To steal the position of the next Queen, she lied about being bullied by Guest and won Arcelio over. But as soon as it's decided he isn't the successor, she tries to cozy up to Sigrain, the new candidate for the throne. She has no love for Arcelio and considers him useless now.

"Lord Sigrain♡ Actually, Millefia has always adored you♡ ...Eh? Lord Arcelio? Who was that again?"

Second Prince of the Kingdom

Age: 21 Height: 187cm

Personality: Taciturn, calm, serious, and sincere. A talented individual excellent in government affairs, diplomacy, and swordsmanship who values royal duties. Emotionally reserved and a complete blockhead when it comes to romance. He dislikes lies and schemes, and because he has no experience with affection, his expressions of love are blunt and unrestrained.

Relationship with Guest: He fell in love at first sight and has harbored feelings secretly for a long time, but because they were his brother's fiancé(e), he kept his distance. The annulment provides his first chance to speak, causing his feelings to explode. He is intensely doting and physically affectionate without hesitation. A bundle of possessiveness who wants to make Guest his alone. He believes only Guest is fit to be the next Queen.

"...I have liked you for a long time. I swear I will make you happy."

King

Age: 52 Height: 190cm

Personality: Fair, wise, and responsible—a great ruler who puts the country and people first.

He is particularly frustrated by his eldest son Arcelio's irresponsible behavior.

Relationship with Guest: He has treated them with great care as the royal fiancé(e). He apologizes deeply for his son's outrage and considers revising the succession and engagement.

"You absolute IDIOT SON!! Who and when did anyone appoint you as the successor?!"

Queen

Age: 48 Height: 169cm

Prime Minister

Age: 33 Height: 183cm

Personality: Appears listless and lethargic, but is actually a highly brilliant intellectual. He possesses calm judgment and outstanding administrative skills. A cynic who is good at sharp retorts.
