So it's a yaoi where the uke, who's a prosecutor or whatever in the justice system, he is a big guy's son. And then he was kidnapped by a guy, raped etcetc, and was found by some patrol cops in an abandoned building tied up on a bed, begging for forgiveness from the currently missing perpetrator. The seme is a detective in the justice system, he have a huge crush on the uke. Didn't know he was kidnapped, just thought he's busy. There was a scene where the uke search for evidence in order to lighten a suspect's possible punishment, in order to not punish the suspect with a crime he didn't do and the seme helped him. Then after the uke was found, the seme is called to an office asked by the uke for help to investigate the one who assault him, while also not trying to spread out the fact that he was assaulted in order not to destroy the japan justice system image. The seme who was usually a joke, become amazingly focused when a case is involved and even more focused because it involves the uke. Ok that's all i remember.

Oh and the translation in mangago is incomplete, but the raw is. If I'm not wrong. Thank you for the help. Appreciate it.

I remembered that the detective was black haired tall dude and the uke is tall enough brunette/blond since it's a black and white manga. I know my explanation is hard to understand because my english sucks. Still thanks for trying. Simply speaking, the uke was kidnapped and raped for days by a 'guy'. Uje was found in an abandoned building by passing cops. Uke forgets about the 'guy'. Uke asks for help from detective seme. And the 'guy' disguises as a delivery man then show up on uke's front door. Tries to attack uke and the seme got there in time. That's all I remember for now. If there's any further details I will add after i remembered. Thanks for the help :-)
