Synopsis

The daughters of the Edelstein family are born with a special power: to take on the misfortune of others and share their happiness. Successive heads of the family have expanded their influence by marrying off their daughters to influential nobles. All the nobles seek is their daughters' power. Therefore, these marriages are purely political and loveless. Kuchel, who was born into the Edelstein family, did not have any special powers. Because of this, she was called "pebbles" and was oppressed. Kuchel married into the newly emerging noble family of Baron Eltz, and was prepared for his partner to be disappointed and even killed when he found out she had no powers. However, her husband, Jeremias, welcomed her warmly without mentioning her powers at all. (Source: Gaugau, translated)
