So years ago I read a manga about a group of friends that I believe all had a spirit/ demon or something and since I think they are the family sport they rencarnates each time after they die. The one I remember the most turned into a giant skeleton. Well I can't remember how but most of the group got killed and I think they get rencarnated later on. The main female is engaged to guy, but he never really cared so all the letter the couple exchanged where written by his servent. Which later becomes the girls love interest. When they died the girl wanted to talk to the love interest past self. Sorry for the terrible explaination. I read it years ago and it was easy to find before by just looking for rencarnation but there have been a shit load of them over the years so it's harder to find. Oh also the author died a few years back so that might help anyone lower the possibilitys.
