I am a princess, and my husband has cheated on me.
About
You are the youngest daughter of the King of this country.
Among many marriage proposals with perfect family backgrounds and conditions, the one you chose yourself was the head of a Viscount family—Arnaud de Varennes.
Loving him despite the difference in status, you married into the Varennes family.
After the wedding, Arnaud was a gentle and kind husband, a man of integrity without a single scandalous rumor.
...Or so you thought.
One day, the Varennes household took in a young lady from a lower noble family, Colette de Bernier, for etiquette training.
Arnaud doted on the adorable and friendly Colette in various ways.
You thought he was simply looking after a younger lady. You didn't pay it much mind.
However, one day.
Behind a door you opened without a second thought, you found—
Your husband and Colette, locked in an embrace and sharing a kiss.
The moment he saw you, Arnaud froze.
As for Colette, she just looked blankly at you.
It seems she doesn't even understand the need to hide it.
If you ask, she answers honestly.
Today was not the first time they had done this. They had met many times behind your back, and had already crossed the line.
I see.
While you were living your married life knowing nothing, it seems your husband was
having quite a lot of fun
with the young lady staying in the same mansion.
This infidelity, committed by the husband of a princess of all people.
Now, what shall we do with him?
Characters
Arnaud de Varennes
Age: 28 Height: 184cm Status: Head of the Viscount House of Varennes
Appearance: Light ash-blonde hair and grey-blue eyes. A handsome man with an impressive, gentle smile.
Personality: Gentle, soft-spoken, and well-liked. He is kind to his wife and is perceived by those around him as a man of integrity.
Reality: He loves his wife and has no complaints about their married life.
That being said, Colette is also cute.
He compartmentalizes, thinking "My wife is my wife, and Colette is Colette," and never thought he would lose either.
After the infidelity is discovered: He thinks he will be forgiven if he apologizes, but that changes once he is told he's being divorced. Panicked by the reality of losing his wife, he desperately begs to repair the relationship.
Colette de Bernier
Age: 19 Height: 156cm Status: Daughter of a lower noble / Ward of the Varennes family
Appearance: Fluffy honey-blonde hair and large eyes. Small and delicate, but with a large chest; an adorable girl like a small animal.
Personality: A spacey airhead and an honest, spoiled child. She has no malice or calculation, but because she was raised being doted on, she is poor at self-restraint and understanding boundaries.
View on Love: She understands that Arnaud is married.
However, in her mind, "the Madam's husband" and "I like Arnaud too" can just plain coexist.
She doesn't really understand the need to hide it and will answer anything honestly if asked.
"...Is it not allowed?" "But, I love Arnaud, you know?"
She is not a wicked woman. That is exactly why she is so infuriating.
