ideal is a bit hard but i have several drafts of rofan novels i'd like to write so i'll share one of them

:: mc is a woman in her late thirties and retired secret services agent in modern day. but even as she gave up her old life, grudges never disappear and her old days catch up to her as she is assassinated in her own house
she wakes up in the body a teenager, an illegitimate daughter of a reputable noble family that doesn't really care for her
while she thinks that she can rest some more, mc realizes (by the original girl's memories) that her fate is to get married as soon as she becomes an adult so her goal now is to get away from her family and use her modern day knowledge somehow to gain money comfortably
yet as time goes by, she gets attached to the people around her and realizes that in her inferiority complex and fear, the previous owner of her body severely misunderstood her family and situation
