Fried's contract to be a laynoble's thrid wife was stated almost at the start when the character was introduce back when Benno was looking into the Eating Disease. We later find out down the road that her contracted husband is Dameul's older brother during the shrine maiden appentice ight before the adoption arc.
Myne has her own personal cooks but importance of of recipes is greatly diminished once she starts the school arc. Outside Gutenburg and her commoner direct family, minor characters like Freida, her cooks, the gray priests, etc are more or less greatly disministhed or out right disappears since they are not longer pertanent to the story.
Damuel's romance luck is rotten because of his magic power and noble standing. He's considered a laynoble (lower) with mednoble (middle) magic power. His magic power to high to be of a match for the women on the same level. No mednoble woman wants to marry down and end up become a laynoble. Brigitte ws the only exception because of family issue and she was considering it to bring him up and into her family to help to help manage her family's land. But because of secrets and stuff, he's not really allowed to leave Rosemyne's service. There is one laynoble girl in Rosemyne's aide group that is interested and will possibly match his magic power by the time she graduates but because of the age gap, having to wait for her to come of age, and him being on the dense side, he doesn't see her in that way. It's like a 12 year old chasing after a 18 year old.
