Fake

The Manga from Sanami Matoh has 7 volumes and was published in 1994 in the japanese magazin BexBoy. You can also find a quite good OVA, which deals with a story of the second volume. 

To make it short, Fake is a manga about two cops. Accordingly Fake is full of action, but of course you'll find there a great Shonen Ai Romance between Randy -Ryo- and Dee.  

Randy, halfly japanese (because of it he also have the japanese name Ryo) became the partner of Dee Latener on his first day in the new district.
Dee is really impressed by his new partner ^^;

So Dee decided to win Ryos heart, but thats not that easy, as he thought, because ther are a lot of problems he has to deal with ^o^). First the boy Vicky, who Ryo adopted, when he heard his past (he really likes children a lot!). And Vicky is quite devoted to his new "dad", and so he is also quite hostile towards Dee...

But Dee also have his admirer, from the police district the two work at. JJ is one of my favourite charas (what is fake without his really nice phrase "Dee-sempai"?) and likes Dee a lot! But there will be also a lot of people who are attracted by Ryo... ^^; So... the question is now... will these two become a pair, and also... what kind of police district is this (I sometimes ask myself, if all police cops from N.Y. are gay or bi...!), the only "normal" person is the chief...
