This seemed like and nice manga. When I noticed the small blonde girl - tall dark-haired girl relationship I was apprehensive this would turn into yet another "dark-haired girl has a melancholy secret she needs to be saved from by the blonde MC" story, but that thankfully didn't happen. I actually enjoyed this for a while. The four main characters had some nice interactions. Then the author began to riddle Fuya (can't remember her name) with flaws. She scores below average on tests, has no friends other than the other main characters, can't deal with crowds...
All while every other character got one little foible, but remain depicted as perfectly average characters otherwise.
What a coincidence that it's yet again the dark-haired main character who is the only one of the main characters to be burdened with all of these weaknesses. Not.
I wish writers would stop doing that. Freaks who want to see dark-haired female characters depicted as weak, helpless, flawed and melancholy all the time should not be catered too at all.
