Looking for a yaoi manga

So there’s this kinda obscure manga that i read, and i wanted to read it again but i forgot the title. It was about some detectives at a police station, where the main character was the new guy, and the seme was already working there. They became sorta a crime-fighting duo. I remember the manga was mostly about the crime fighting, and all the romantic development and so on happened very slowly. The artstyle was very distinct, and the men looked very much like men and not boys, if you get what i mean. Though the main character looked kinda cuter than the others. Also, i remember there was one side couple, and i remember not liking them very much, but just putting up with it. My memory might not be completely correct, but i appreciate any help i can get with this!
