Hello,

Looking for suggestions of yaoi manga that has police, or detectives, or undercover missions as the setting of the story. Like the couple meet while undercover or work as partners undercover.

Thank you for everything in advance.

my best recommendation for such a theme are the S (novel) books by Aida Saki. They're BL novels instead of manga but it's a quite good story and fits what you're looking for very well.

Missing Code by Minase Masara and Katoh Elena,
Koujitsusei no Tobira by Shoowa, maybe?
Katekyo Hitman Reborn! dj - Mr. & Mr. Hitman? by Yoneda Kou,
Calling by Miyamoto Kano..?
Deep Black by Mamahara Ellie.
