"From now on, you are my temporary fiancée."

Emilia, the daughter of a poor viscount's family, is shy when it comes to romance and works hard at her side job of embroidery. Suddenly, a blind date comes her way. Her prospective groom is a beastman nobleman, a count. And a black rabbit at that?! She thought he'd be the cute type from the sound of it, but it turns out he's actually a beastman gentleman who's a top-class martial artist and herbivorous animal... Overwhelmed by his momentum, Emilia is marked with a "marriage proposal mark" and becomes his temporary fiancée...?!
