So the MC is an attorney who is basically covering for his little brother who has a messy lifestyle despite being somewhat of a celebrity I guess. The younger brother implied he slept with that dirty old man to get further connections and job opportunities.
The MC went so far as to even masturbate on the dead old guy and make it seem like he was the one who was with him when he died.

This doesn’t even qualify as shounen-ai, it was literally all platonic. Point blank. Nada, nothing of that nature. Two male leads and their growth along with friendship doesn’t equate to shounenai. And anyone who says it does is reaching. Not even a sprinkle of romance.
Nonetheless, still a good story and read.
I liked the story but the concept for all the killing was still way too vague. It could be left up to the viewer to just view it all as symbolic or something actual supernatural. But for me, with it still being unclear it just made it more unbelievable for me.
Still a good read nonetheless
