Reborn, I Rekindle a Century-Long Bond with My Ex's Uncle

Looking for a Story With a Reborn Female Lead and Her Uncle-by-Marriage

I saw a novel recommendation on Weibo, but I think they changed all the character names, so I can’t find the original. In the first lifetime, the female lead gets together with her childhood friend. She only learns that her uncle loves her after he commits suicide. The childhood friend loves the nanny’s daughter and even has the female lead’s daughter killed for her sake.
