Milo's Things

So I’ve been trying to find a manhwa to reread it but I have not found it and I don’t really remember much of it, but what I do know is that in the first chapter the fl and the ml (not sure if they’re the ml or not) were running away from the fl’s brother(?) and that the fl gets killed in the end and she goes back in time I think as her younger self. I also remember that the ml’s hair is black and that the fl and bother may have had light colored hair. I somewhat remember that the fl’s brother had like an obsession with the ml(?) before fl goes back and time. I’m sorry if this isn’t much to go of on but I’ve been trying to find it but to no avail and it’s been driving me nuts. (´°ω°｀)
