I think they will both have a tragic ending and then fast forward to the future reincarnations they finally get together, which honestly im interested to see that too

I would like to counter you theory by saying: there isn't a tag with connection to reincarnation like 'fantasy' for example. And we already get a glimpse of the future on the first chapter which probably is old shinpei reminiscing his memories with satoko (after she died obvs) which is sad but will add angst.
Important disclaimer this is my view on the topic and I didn't mean to be rude and I applause for your positive ways of thinking
Shes been with 3 men right?
Ravis biological father,
yellow haired biological FLs father, and
white haired step-father/adoptive father...
(And abusive parents from other life)
Correct me if I’m wrong but I don’t think they were physically together or in love (white haired step dad). I thought it was more a marriage of convenience like a way to support her and her kids since they helped him out?
No you're right
