Luisa, a senior engineer working for a tech company, unexpectedly fell into a coma while on her way home. When she woke up, she found herself in a medieval town with her own supermarket.There was good news: the owner of the body is named the same and comes from a noble family, and has inheritance rights.There was bad news: it was the Middle Ages!!!While the dark Middle Ages were a viewpoint of the Renaissance, it was more about highlighting the progress of the times, so stepping on previous eras was fine, but it could not be denied that the Middle Ages was not particularly suitable for living, with its dirt, chaos, violence, poverty of material goods, cultural suppression, backward medicine, and low status of women... These were not false.Being in this era, even with her own supermarket and noble status, Luisa still had a headache!So, she had to try her best to change her living environment, but－－accidentally changed too too much...
