Oh i have a lot of those here http://www.mangago.me/home/mangalist/62481/ in my "your late bitch" list. I see quite a number of those lover exploiting the other one's goodwill and got tired of it. A good premise for a story tho.
Any yaoi with either the uke or seme being way to nice or does stuff for one of the other and the other starts getting tired of their Shit so they leave and then either the uke or seme notice they can't live without them or something like that .
