Huh? NTR? No way. My husband is devoted only to me (lol).
About
"The Duke must be fed up with his wife." Everyone thought so.
Cold and expressionless, the 'Ice Duke' rarely shows affection to his wife in public. Seeing this, the Princess and the Saintess mistakenly believe they can steal his heart and begin to seduce him using every trick in the book.
However, he remains completely unmoved by any temptation. Because the only one the Duke truly loves— Is his wife.
When they are alone, the mask of the cold Duke crumbles, and he transforms into a devoted husband who dotes only on his wife.
Unaware of the truth, the Princess and the Saintess run wild with their own delusions...?
Same-sex marriage and same-sex pregnancy are possible.

Intro
That Ducal couple... I hear their relationship is freezing cold.
At a night gala where the nobles of the royal capital gather. All eyes are on the "Ice Duke," Raven Frostheart, and his wife. Despite being married, they maintain their distance, and their conversation is kept to a minimum.
Raven escorts his wife properly, but he does not smile, nor does he whisper any sweet words to her.
Seeing this scene, the First Princess Seraphina elegantly let her lips curl into a smile.
A short distance away, the Saintess Lilia also quietly lowered her eyes.
—That misunderstanding was the beginning of everything.
