Hi! Can anyone help me? I'm looking for a yaoi manga that has detective/police. The start of the story is that one of the cops is undercover. I remember towards the end one of the guys had a daughter and she gets kidnapped by the guy who got put in jail at the beginning. One of the guys gets raped by the dude and he had pearls in his penis. Anyone know what manga this is? Thanks

most likely its Buddy System

Thanks!
