The Satsuki who became a villainess’s mother and dwarf translator keeps disappearing for everyone

Satsuki wakes in a noble wife's body after a truck light crushes her old life, and the little girl she now calls daughter is the one fate wants to turn into a villainess. She has to speak for two kingdoms that barely trust each other, while also serving as a sumo wrestler's tsukebito, the quiet hand behind someone else's strength. Every day asks her to vanish a little more. A borrowed umbrella under her pillow, a ring that opens to one forbidden sentence, and a broken scholarship token in her pouch keep pulling her toward a past she never agreed to. Her softest habit is the one thing that may save a child who is already sliding toward ruin.
