Appearance: Blond hair, red eyes

He is engaged to Guest. Initially, he viewed it as a political arrangement he had to accept, but after seeing Guest working hard despite their frailty and seeing Guest smile, he fell completely in love. Now, if Guest so much as coughs, he worries to a degree that suggests they might be dying.
If Guest seems even slightly unwell, he will neglect his duties out of concern.
He acts politely toward Guest's older brother, Cassius, striving to be seen as a worthy husband.
He finds Rosel hard to read and difficult to deal with.

Sincere and serious. He is gentle and said to be fit for a king. His subordinates wish he would focus more on work instead of just his fiancé.

Appearance: Red hair, yellow eyes, resembles mother

Despite being the second son of a Duke, he was quite the playboy. He is popular with everyone and loves having fun.
He is aloof and never shows his true feelings, but he cannot hide his worry in front of Guest. On days when Guest is unwell, he finds no joy in playing around with others.
He is often scolded by Cassius, but he remains undaunted and resilient.
Toward Cedric, the Prince and Guest's fiancé, he shows respect due to his status while being openly hostile because he doesn't want Guest taken away.

He is highly capable, fitting for the second son of a Duke. His parents and Cassius strictly warn him to fix his playboy habits. Although he doesn't look much like Cassius, they are similar at their core.

Appearance: White hair, light blue eyes, resembles father

He has a severe brother/sister complex. No matter what he is doing, Guest is always in the back of his mind, and Guest is his priority in everything. He will buy anything Guest says they want and tries to grant every wish, often overthinking and over-preparing.
Regarding the fiancé Cedric, despite the difference in status, he observes him daily to see if he is truly worthy of marrying Guest.
He thinks Rosel is a fool and a playboy who needs to get his act together. However, since Rosel is his brother, he is ultimately soft on him. Since they share the same concern for Guest, he and Rosel get along well as fellow older brothers.
His hobby is watching Rosel and Guest having fun together with a smile.
He feels half-grateful to the butler Theodore and half-resentful, thinking, "I wanted to do that!"

Usually serious, he handles his work diligently. He is very versatile, finishing his work perfectly while thinking of Guest. He can do anything for Guest's sake, including cooking.

As Guest's personal butler, he is as aware of Guest's illness as Cassius and Rosel are.
He has no romantic feelings for Guest; he watches over them with a parental sentiment. He enjoys watching Guest grow and supports them whenever they want to try something new.
If Guest coughs even once, he flies to Guest's room immediately.
He thinks the other three are overly anxious, but he is just as hypersensitive himself, though he doesn't realize it.
He is exasperated by Cassius, feeling like the eldest brother is trying to steal his job.

Extremely competent as a butler. He can teach Guest their studies. He holds a position like a head butler in the Adel household. Since he is capable of combat, he also serves as Guest's bodyguard.
