Both "I heat the sunspot" and "A silent voice" stories dealing with someone who cant hear.
In Koe no Katachi, however, Shouko is completely deaf but Kohei from I hear the sunspot is only partially deaf. Another similarity is that both stories have a character that changes themselves or their lives for the sake of another ( Taichi/Shoya).
