Morio Kurokawa is the toughest-looking tough guy around. Yukiko Akaza is a self-possessed girl with a vision impairment attending a school for the blind. The whole city fears Morio, but Yukiko sees the real him--he's a soft sweetheart who's just searching for his place in the world!

As Morio and Yukiko continue to grow closer, their friends do too--or try to, at least! Personalities clash between folks leading different lives, but can Yukiko help her best friend, Sora, use her love of running to help the group embrace each other's differences?
