not sure if it's the one but similar stuff happens in itou-san https://www.mangago.zone/read-manga/itou_san_kuraka_sui/
Unfortunately that's not it. The manga I'm looking for is just a short one shot.
Still, thanks for answering! ٩(๑❛ᴗ❛๑)۶
The only thing I remember is that uke went to see seme, only to find seme with some shady guys discussing something related to the underworld, i think? They found the uke eavesdropping on their conversation and the boss have the seme shoot uke to death. Anyone knows the title?
