Man, the author really lost sight of what the story was about. These antagonists are getting more and more ridiculous with each arc. The MC's relationship with Ayame has also been put on hold because any further progress would resolve the issue and end the story, so instead we get "filler", keeping the status quo while throwing increasingly insane situations at the gang. I mean, this is already at the level of targeted harrassment, but the school does nothing even though the target of the harrassment was previously assaulted and nearly raped.
