Ayumu's behavior is honestly creepy. I'm not talking about how she's interested in girls, but how she comes across as a creepy stalker. On the positive side we at least see Yuu not being stereotyped as a creepy emo stalker in regards to Ayumu, but stalking behavior is stalking behavior and in no way is it romantic. If Ayumu's behavior simply stuck to glomping Yuu things might not be a problem, but she eventually starts following her despite not being very welcomed as if she were a complete ditz. For her voice I kept imagining a really squeaky sweet voice dripping with gross optimism. I also felt her design was a badly rendered version of another artists character.
Yuu on the other hand takes the act of pessimism to the extreme. She has some kind of social disorder, but the one-shot never goes into any depth beyond having her whine about how her father abandoned her and then her mother and thus she doesn't even try making friends. Social disorders aren't that simple, and in reality her attitude seems off with her having a loving grandfather. Her character design is flat as if the writer didn't use an actual reference.
My enjoyment for this particular piece was low. There were to many things making me bang my head on this one.
