Sakana no Kokoro

High schooler Kosei Matsumi spends his days sketching fish at the aquarium, hiding his eccentricities from the world. When he meets classmate Mao Takizaki—a girl seen as aloof and distant—they sense a shared solitude and slowly form a connection. Joined by Ayako Mashima, a souvenir shop worker, the trio begins exploring the depths of their own hearts.
