Nobuko is a very relatable lead, with her social anxiety and all that comes with it. She’s so sweet and shy that she makes you want to see good things happen for her. Every small victory she gets is appreciated by her and the reader, no matter how seemingly insignificant it is. This was just a personal thought, but she seems to be on the spectrum perhaps? Her crush, Irie-kun, might also be as well. I don’t think that will be officially stated or anything, but it was just a feeling I had.
