Ohhhh...
Then have you read this one: http://www.mangago.zone/read-manga/nibiiro_musica/
I mean it’s not exactly what you asked for but I thought it was kinda related??? Actually now that I think about it, this has nothing to do with what you asked for but this manga came to my head
Along the plot of the seme moving on to someone else while the uke was unconscious or away. But they eventually got back together.. something similar to 'ways of parting/ a way of life' except that the seme got back with the uke..
