I am looking for more stories that happen in the red light distric with at least one of the main characters as a male prostitute like Ginchou Kidan or Namida mo Tooku - Aonibi no Nemuri or Seinen Horeyasuku, Koi Narigatashi.
Thanks for the help!

Gyokusenbou Yawa

Miyamoto Kano's Lovers and Souls. One of the characters becomes a hustler in a gay district. His story continues in Rules.

Also try Heart Strings and Last Client.

Thank you for these suggestions! 🙂

I found some, I'm posting here so other people who search this theme can find.

Roumantei no Juunin
Flaming Ieraishan
Koi no Okite

Some more 🙂 :

Mede Shireru Yoru no Junjou
Kawaita Yoru no Machi wo Oyogu
Shounen Zanzou

Here is yet to come a witty comment on love

Great suggestions, thank you so much!
