Synopsis

After six months of marriage to King Sieghart of Luberia, Rosaline has been untouched and has become a "decoration queen." But she was not allowed to spend the night with Sieg because of a certain curse!　 Unaware of this, Rosaline made up for her isolation by doting on the rabbit that comes to visit her bed every night, and by chance she ended up working as a waitress in a diner in town.
