Shounen to Kusuriuri

Amane lives with his mother in a village, unaware that he possesses an unusual ability—when he touches someone or something, he hears their inner voice. His friends learn about this and begin spreading harmful rumors, claiming he is a monster. As a result, his mother takes him into the forest to escape. Over time, his power does not fade, and his mother's condition worsens despite their hope for a cure.
