Mother-in-law, but I don't like father-in-law conflicts

“…… Mother, please behave properly." Our perfect daughter-in-law (older) didn't seem to like me. "Grandma...... No, Duchess, can I go to bed today?" In the midst of this, the aristocrats I had cursed began to regard me as my grandmother from my hometown. She was married to an old duke, but her husband died the day before the wedding. She suddenly became the duke's eldest wife. By the way, the son and his wife are older. "Let's live quietly." A full-fledged conflict between the rich and the poor. Morb modern people whose social circles are not understood.
