They're both about women that get reincarnated as the young version of the villainess from an otome game. They're part of the nobility and try everything in their power to avoid the bad ending. They come to be loved by their family and most people around them, while being regarded as very smart, especially for their age. There is also magic involved.
Both works have a shoujo demographic.
