Hey guys does anyone know a similar manhwa where fl goes back In time to save her unrequited love because she couldn't stop dreaming about him and she does it in multiple ways but realises she is just not the one for him and like he would always fall in love with this one girl only. however bad the senerio became and at last I think that guy tells fl that maybe it is just his fate to love her and stuff fl tells him to not go to that girl and their is this guy who is in a similar situation as the fl and I think the ending was not happy that guy still ends up dead at last while fl was still not over it or something.

Ps- I am asking this because I this is that manhwa but I don't see such spoiler and everyone seems to be happy with the way the story is going which unlike that manhwa before everyone was so fucking upset but I Don't want to spoil myself reading the ending nor do I want to suffer the same so please tell me If u think it's the story I am talking about and if it's some else please tell me the name of that if u know
