This drama is adapted from a comic of the same name, telling the story of Aoma (played by Shunta Sono), who loves to ignore everyone in the club, but only opens his heart to his predecessor Kotori (played by Mizunai).This special relationship began on a cold rainy day - Aoma was trembling because of the cold and was caring and warmed by the enthusiastic Kotori.

From then on, the young engineering man who was afraid of the cold and arrogant began to devote himself to the caregiver of the seniors who were slow to fall in love.
