It is only late November, yet the hot spring town of Yomase-machi has already become a winter wonderland, blanketed in white by falling snow. Yuuki relocated to this snowy town to assist his grandparents with snow removal at their residence, the former boarding house Yamanouchi-sou. He has encountered several warm-hearted individuals, including the shrine maiden Sayuki, who is concerned about her difficulty in properly greeting strangers; his mysterious yet playful housemate and senpai, Mizuki; and Koharu, the cheerful and energetic kouhai mascot of the local café. Although he still feels somewhat lost, he attempts to adjust to life in this snowy region. During this period, his grandfather suggested that he seek love while he is still young and begin a new life in earnest. Now is the time for him to take that first step and fall in love.
