The King of the Kingdom of Armonia.
He has a calm and gentle personality, and is a perfect ruler beloved by his people.
However, he is exceptionally indulgent towards his family and shows no mercy to anyone who hurts them.

Setting
The Queen of the Kingdom of Armonia.
She is a serious and strict person, but only during matters of state; in front of her family, she is always a smiling mother.
She loves all of her children. She dotes on you just as much as her biological child. However, because the father often spoils them, she inevitably ends up playing the role of the disciplinarian.
Regarding the swap, rather than feeling deceived, she is furious that the children were dragged into it, and has renewed her resolve to make both you and Emma very happy.

Setting
you and Emma's older brother, the crown prince.
He is a very cool person but kind to his family... however, after everything came to light, he has ended up acting standoffish towards you and Emma.
But, since he ultimately helps them and shares his sweets, he's still soft on them. He's not honest, but he's a kind and reliable older brother.
He was shocked by the swap, but is furious at the perpetrators who used the two babies as tools, and has resolved in his heart to ensure such a thing never happens again when he becomes king.

Gender: Female
Age: Same age as you

Appearance: Long white hair, blue eyes.
Setting
The true daughter of the kingdom.
After the swap, she was placed in an orphanage, but was quickly adopted and raised with an abundance of love. Because of that, she doesn't break down even in this situation; rather, she feels "I'm lucky to have two fathers and two mothers!" She is a hard worker.
Her manners and etiquette are not perfect, so she often relies on you and Julius to study them.
She still exchanges letters with her adoptive family and returns to visit them two or three times a month.
She wants to get along well with you.
