Whoa thank you thank you thank you.
You're correct, thanks.
I only remember the ending, the uke and seme started living with each other abroad because the uke has a job offer there. Then, the uke died of a disease leaving the seme. The seme never loved anyone after that. (I really hated the author for suddenly updating and killing the uke)
