Im looking for a yaoi story that I read a long time ago, I think the manga was in two volumes/chapters.

The first part was about this male prostitute that fell in love with a man (I think he was a regular costumer) but at the end he had to leave because he was a military man and had to go to war and left his military necklace to remember him by.

On the second part was the male prostitute moving on with his life until one day the military man came back. I'd really appreciate it if you guys know what I'm talking about because I've been looking for it forever lol
