On that cold place, maybe you can find warmth

Haunted by a tragedy that shattered his world, a brilliant but emotionally frozen engineer, Shunsuke Yamazaki, accepts a transfer to the remote, snow-covered town of Kamikawa in Hokkaido. He seeks refuge in his work, using his demanding new project as a shield against a grief that has left him numb.

His quiet solitude is soon interrupted by the warmth of his new colleagues, particularly the kind and perceptive Mikoto Komaeda and her bright, energetic teenage daughter, Amy. As Shunsuke is drawn into their lives, he begins to feel the frost around his heart thaw for the first time in years. Yet, he can't shake the feeling that their kindness stems from something deeper than mere hospitality.

Both families are bound by a past tragedy, and a life-altering secret waits just beneath the surface-a secret that Amy carries within her own chest. In a place defined by its biting cold, Shunsuke must confront the anniversary of his loss and discover if the warmth of a new connection can truly heal the deepest of wounds.
