Giselle has lived a hard life — mistreated by her uncle’s household and sent into an arranged marriage with the knight Claude to strengthen ties with the royal family. But after her husband vanishes after their wedding night, and she’s stuck doing servant-like chores with no affection or companionship, her life seems bleak.

Everything changes when she accidentally hits her head and suddenly remembers something shocking: in her past life, she was an Osaka auntie! With the heart and spirit of a boisterous Osaka obachan awakened inside a gentle noblewoman’s body, Giselle decides to stop being a doormat. What follows is a hilarious, heartwarming, and romantic comedy as she tackles her marriage — with renewed confidence, outspoken charm, and a lot more sass — and discovers that love may have been right in front of her all along.
