Himuro is an office worker who belongs to a race of supernatural beings with strange powers. Whenever he is deep in concentration, he subconsciously plunges his poor coworkers into a close rendition of the Arctic. Even so, contrary to his icy powers, Himuro is a warm and kind person. He likes flowers and cats, but alas, he cannot get too close to either. Himuro has a soft spot for his colleague Fuyutsuki, a calm woman who has a knack for providing simple solutions to his unconventional problems. Whenever Fuyutsuki does something for him, a snowstorm of emotions builds inside Himuro's heart, and he fails to notice the raging snowstorm he causes on the office floor. Thanks to his snowy tantrums, Himuro's feelings are apparent to everyone but Fuyutsuki. However, fueled by immense adoration and desire, Himuro is prepared to do whatever it takes to capture her heart.

Kind-hearted Himuro-kun is unfortunate: when in deep concentration, stressed, or flustered, he involuntarily creates blizzard conditions for himself and anyone in his vicinity. During one such incident on the first day of his new job, Himuro-kun encounters the beautiful Fuyutsuki-san, who helps him break out of his nerve-induced ice. As it turns out, Fuyutsuki-san is his new coworker. At the office, the cool-headed Fuyutsuki-san offers simple and rational solutions to Himuro-kun's icy dilemmas-everything from helping him garden without freezing his plants to ensuring he does not melt during their tropical work retreat. Every time Fuyutsuki-san does something kind for him, the tempest of emotions he experiences inside embarrassingly manifests on the outside. As a result of the frequent snowstorms, Himuro-kun's feelings for Fuyutsuki-san are impossible to hide. Even though Fuyutsuki-san is unfamiliar with love, Himuro-kun remains determined to repay her kindness and warm her heart in any way he can.—MAL Rewrite
