When Kaori suggested uploading Shizuku's new novel online, did it bother Shizuku because of the painful memory of the last time she submitted a novel online? Or because the new novel contains her true feelings for Kaori, and so she doesn't want anyone but Kaori to read it?
I thought it hurt her because it was supposed to be a novel just for the two of them. And when she suggested that, it kinda seems like it pushed the mutual feeling or own thing away?
Though I would also say it is because it is scary to open up your own feelings to others and going from the person she wants to trust the most to the whole internet world? That‘s a gigantic leap.
