Let's meet in the mountains and get to know you through the mountains.

The sound of the wind, the sound of insects, the sound of water flowing in a stream, the sound of your heart...
Shun Kagayama, a man who was fascinated by and loved mountains, says, "I feel alive only when I climb mountains."

One day, he meets a lone woman, Tsubaki Sendo, who looks nothing like a mountain climber. Unable to bear the sight of her, Kagayama accompanied her and found out her "reason for climbing the mountain"--?

A story of a woman who lost her "precious thing" and a man who met his "precious thing."

A sentimental and magnificent mountain climbing love story.
