It was this one. Thank you so much! I just kept randomly thinking of it and it was driving me nuts not being able to remember it.
Welcome enjoy it's good story it also has live action Japanese drama worth watching.
I read this years ago but don't remember the name. It was a real tearjerker and sort of unique yaoi. Anyways...the story was about these two men who would end up together then split up but miss each other then end up together again just to split up again. Rinse and repeat until they take a huge break from each other I think until they get middle aged or a bit older than that then they end up together for good until they grow old and die. Sorry if this isn't a very good explanation. That is all I remember since it has been so long. I just felt someone might know what I am talking about since I have read a lot of yaoi and not came across anything quite like this particular one.
