Before everything got wiped here I remember reading a BL manga about a serial killer (not sure, but he does murder, so probably assassin for hire or smthn like that) and a regular office worker dude. The killer guy was the top iirc and was pretty obsessed in a beige flag kinda way to the other guy. The art was pretty too.
