Although the morning forecast predicted milder temperatures than usual, it turned out to be completely wrong. Chika and Ryuta, dressed too lightly for the weather, shiver uncontrollably from the bitter cold during their date. When they return home, unexpected troubles strike—the air conditioner breaks down, and even heating the bath takes much longer than expected. As a result, their body temperatures continue to drop, worsening their suffering from the freezing cold. In the midst of this, Ryuta jokingly suggests that if they were stranded in a snowstorm, the best way to survive would be to hold each other naked. Chika reacts with a mix of surprise and confusion. A slightly humorous yet poignant story unfolds, capturing the harsh winter chill and the deepening intimacy between the two.
