really? iirc, the next heir can claim you. Her sister can claim you even if you do nothing with herIt's suggested that since Tomoe isn't yet the official heir (next leader) her mom or her sister could claim you as husband for themselves and Tomoe losing her position and being potentially the sidedish rather than the main girl (main in regard to her clan)
I mean it does not matter what you do with the mother. It should be about Tomoe's feeling or something that idk
