The Tigers are doing great against the Dreams thanks to Kiyo's help and it reminded Azumi of his past as a sprinter once again. I kind of feel bad for his father, struggling to move on over the death of his wife and seeing more and more of her in his own son who had become an excellent sprinter while he had nothing but strict piano lessons to offer him.
He had achieved a spot in the nationals but it looks like his leg's nearing the point of no return after that.
