Finally an actually character developing chapter. All the series till this chapter feels like a filler now.
They pulled the classic misunderstanding element now, that will surely be resolved later with something like "we didn't do anything, I just closed the curtains because we were gonna play table tennis and she's too shy so doesn't want anybody to see her playing" or some stupid unbelievable reason related. It's not that I hate the manga or this kind of plot device, but it bothers me that after a good chapter with real character growth, they pull this cliche and ruin the progress with the classic superficial jealousy.
