Searching for a Yaoi Yakuza/Police

I was searching this yaoi, which is a love story about a yakuza heir with a discutibile sense of fashion (he wears mostly animal prints) and a policeman. I remember that returning from a visit to the family of the first guy they got in a car crash. The mafia guy became friend with the colleagues of the policeman, though they don’t know until some point who he is son of.
If you know the manga you’ll have my gratitude forever.
