Jongin has finally moved with his aunt in the countryside, hoping maybe to get better. That's when he meets Kyungsoo, the weird kid who lives up the hill whose skin is always cold and heart is always warm. They were in search for a friend, someone that could understand, but what if they find something more?

Kyungsoo is a college student with a fear for silence and the feeling of loneliness, Jongin is the bright kid with a passion for dance and a heart lighter than his feet, Sehun has a secret relationship with someone he has never met and Yixing has now shut his thoghts to the world. But in those summer days, everything seem possible under the sunlight.
