Smack-dab in the middle of class, a small group indulged shamelessly in sickly affection without considering just how inconvenient and annoying it was to everyone else. This situation was known to all as the “school’s harem.”
One day, Shinji lost it after hearing a particularly irritating remark from the guy at the center of that harem. He then verbally beat that obliviously annoying dude and his collage of annoying girls.
Upon witnessing this, one of the harem heroines took an interest in him. Thus began a mysterious and unconventional romcom, defiant of all logic and evidence.
