searching for an yaoi

soo i read this a while ago on bato and i cant find it on any site so bear w me
it had a title with something along the lines of the boundaries/borders of love and it had an action storyline that was PHENOMENALL but i cant remember the exact name and cant find it i really want to read it again
the mc was a brown skinned man(probably black but god was his skin colour ashy) and the ml who is the uke was a fair skinned man with black hair i think i partially remember a scene where the white one was admitted to the hospital and it was something about some hidden cameras or mics idk PLSSS share some details if you know what im talking about!!
