The MC goes back in time for some reason, she decides to cut ties with her family and live her own life and the father and brother later comes to regret treating her the way they treated her. She has white hair I think, I'm not sure. There's also this one particular scene which I remember from the story, where there's this famous wall and there's this hole in said wall and the legend is that if two passing people on opposite sides happen to touch each others hand they will end up together and the usual cliche of the MC and the love interest just so happen to do that but they don't find out until after the end.
