helppp

So I read this manhwa before where the genre is straight. It starts with the FL being transmigrated to a novel as a villain who's about to die (she has pink/blonde hair I think) and all the potential ML's where at her house. One of the ml is a knight with white hair I think and the FL has sickness and instead of being a bad villainess, she chose to accept her future where shell die bcs of her sickness
Please helppp
