Long hair is a pain to maintain, but at least you can say you've got long hair. Medium length has all the disadvantages and you still don't have long hair.
I've been keeping shoulder length all throughout my life, and it still gets annoying. A long hair sounds like a new world of pain and annoyance. Kudos for the chibi for getting through all that.
There is this youtuber I follow that is the paramount defender of anime girls with long hair... He chooses waifus based on hair lenght and even has disregard towards the 'Important Haircut' trope...
Pretty funny how this chapter stands against his very being... to the point that his most loyal followers love to tease him about it...
But to be honest... Miyano's character design really loses a lot with short hair...
