Damn the author is so good. I was a fool for thinking the majority of the development would come from Taira and he'd be the one to confess leaving Azuma a bit confused at first. But Azuma unwittingly helped Taira a lot, leading to some self-improvement on his part, which gave him the confidence to help her in turn, and now each is learning their true self-worth thanks to some assistance from the other. It's a beautiful thing.
