I discovered this story yesterday and it has captured my heart entirely! This feels like a breath of fresh air, after which you suffocate. I would applaud the author, if I could, for the fact that they can display the emotional and physical burden that is placed upon musicians from an early age, as well as for asking the question "Do you really have to be a genius?" and that there is nothing shameful in accepting that you aren't one and in seeking help when necessary. The way Tetsuo reacted to Ikumi's brilliance further shed some light on my personal life, since I was also a brilliant child, yet suffered from bullying at school for reasons I couldn't comprehend back then.
Thank you very much for translating this manga! I know how much dedication it takes, so take care of yourself and be happy that you have made at least one person's heart race and smile!
