Set in Japan, Jane is an ordinary girl who goes to the countryside every summer break. One day, she stumbled upon an odd man. That's when it all had begun. Every summer, she goes to him. Every summer, it's just her and him in their oasis. As the girl grows, so is her treasured feelings for him. But even though they're so close, everything seems so far away. Falling in love for someone is not based on how they look, it's loving someone for who they are. His identity remains to be a mystery, but she only has her eyes on him, the masked man.
