@Shuraemyyyyiii What i meant by nonexistent is that, even if Akira can be kind to others, she didnt saw in Mayuki someone in equal ground but instead someone bellow, that she felt sorry for. So regarding Mayuki as an individual the version she saw of Akira being kind was nonexistent. That version of Akira for example would never think of Mayuki as a nuisance in her way. In a sense, when i consider the inner feelings we saw from Akira regarding Rin happines and Mayuki interference, the only thing i can summarize is that she by far is not someone i would want near anyone i like.
I feel like the author didnt really weight properly how Akira actions, reactions, thoughts and feelings would affect our view of her. For me, what i saw was a selfish, possessive young girl with a superiority complex, that i would never want to be too close of the always kind and loveable Rin or the cheerful and bright Mayuki. That wouldnt change even if she did get time to develop. So i guess the flaw was on Arkira character design.
Either way, if theres one positive thing i could squeeze out of the disappointing conclusion we got, is what i mentioned previously about the fact Akira still seemed out of place even after the forced development. But was still something so small that couldnt by any chance erase the frustration of seeing her kissing Rin.
Tbh, i understand the author stand of trying to conclude the story as it was primarily planned. But at the same time, i would rather please the viewers with a more suitable conclusion given the existing development than throwing a half-baked envisioned idea and force us to swallow like we're a bunch of idiots. Is not like a end with only RxM together would betray the story, after all there was a existing triangle as promised, it just didnt need to end with the 3 together. But sadly, i suppose the author really wanted to prove a point or share a experience.
