Synopsis

I'm a decorative wife... I love being a waitress during the day and a fluffy rabbit at night! Roceline has been married to King Sieghart Luberia for half a year and has become a "decorative queen" without being touched during that time. That is because Sieghart is cursed and can't spend the night together! Not knowing that, Line doted on the rabbit who came to her bed every night, and by chance she decided to work as a waitress at a restaurant in the downtown area?! (Source: Kadokawa, translated)
