Way back I found a manhwa accidentally and read it just because I was bored but the plot was so good I could not put my phone down after it, but at that point in time only a few chapters were out and now I want to read it again, I cannot remember what it is.
Here are the few details I can remember: the female lead (FL) was a noble, she got betrayed somehow and in the end she killed herself. She got reincarnated to her younger self and vowed to never get herself near the life she had before she got reincarnated. At some point in the story, she got reincarnated a few times and one time was she ran off with a painter. They had a simple life but a happy one. She had a kid with the painter guy but her brother found them and brought her back to her family. Her brother killed the painter and her father wanted to kill her child too and make her the second wife of a noble older guy. At the end, she killed herself and her child, then woke up, seeing she got reincarnated again.
The female protagonist has ebony black hair. She's from an aristocratic family. Before she died, I think her husband was royalty and somehow caused her death too.
