For me the irksome feeling don’t come from the characters being super ordinary human or anything like that, it’s where the story starts. OreGairu started with the main character meeting another loner who’s frank and honest, which kick starts the events. It got the ball rolling immediately. This one kind of start at the exploring the setting. Unfortunately, the setting is mundane and uninteresting, thus the readers will have to go through all of this before the story introduces us to the main meat, the central conflict, the theme of the story. OreGairu, as mundane as its setting is, always dive head first into its theme, with events revolving around the central conflict and all of the characters have some sort of stake in it. Apparently, as someone have enlightened me, this is the sped up version. The author had to be some kind of literary genius on Hibiki’s level to be able to keep the reader’s interest through all of these mundanity.
