Newly-minted office worker Himuro may look human, but he’s actually a descendant of a Yuki-onna, or snow woman, which means he inadvertently produces snow or ice whenever he gets especially fired up or emotional. Meanwhile, his human colleague, Fuyutsuki, is an outwardly stoic young woman who is nonetheless very kind and sensitive to others’ needs. When the two meet on their first day, sparks soon fly, leading to a variety of somewhat unusual situations.
