Hope my profile picture helps but its about 2 best selling male prostitutes in an older period of japan in the end they decide to run off together

Can't see the profile picture very well, but from the summary I think it's Mede Shireru Yoru no Junjou https://www.mangaupdates.com/series/v0o8j28/mede-shireru-yoru-no-junjou

I've read it recently so I remember it was about two best selling male courtesans in Edo period. They grew up together in the brothel and were friends, later on they became bickering rivals and eventually lovers. In the end, they run off together (well, not quite, but I don't want to spoil if you haven't read it).
