It’s kind of funny how in a larger perspective when people question at the whole point of the Shiho issue or existence altogether. When this whole forum is proving why at some point whether it’s executed well or not, there will be a “Shiho” of some sorts added to a story. In a matter of a few days, this forum lit up like New Years Eve, simply just because they want to argue about the good or bad points of a character and the events it follows as if it’s a trial.
At the end of the day, whether consciously or subconsciously our brains attach more to negative things than to positive. Shiho was that to this story, we want to pick off flaws, we want pick a things we feel don’t belong, we could’ve so easily just dropped it and just started reading another. By of course we didn’t, some wants things to turn around positively, some want to see it all burn, and some of us just want to write our analysis and thesis about the whole thing. Whatever it is, It doesn’t matter if it’s good or not, it gets engagement anyways and that attention is what matters in the end. It’s pretty much the whole reason why this manga got picked up for an anime anyways, the whole drama with Shiho has gotten so much attention whether we like it or not. If the story just continued with Yori and Himari’s, even if it’s just nothing but pure unadulterated fluffiness done well, that in itself wouldn’t have made it stand out enough to be noticed for an anime. Things getting adapted only tend to care about pre-existing sales, the trends, or the opportunity to profit of something, just take a look of majority of anime’s getting picked up from subpar yet profitable (harem) light novels.
