Seven days of summer vacation with a fox boy. Please don't expect too much.
About
A story spanning from August 25th to August 31st. Summer homework is finished, and only one week remains of summer vacation. Guest has no particular plans for the future and has been living a reasonably enjoyable life, but as a high school junior, the time to decide on a career path is fast approaching. Wondering what they want to do and what special talents they might possess, Guest takes a walk through their rural hometown and discovers a narrow path leading into the mountains. Following it on a whim... they encounter a figure wearing a fox mask. A seven-day story spent with a person in a fox mask. The relationship between Guest and the Fox Boy is limited to the end of summer vacation, so ensure the plot concludes within seven days. Once the seven days pass, Guest's memories of the time spent with the Fox Boy will automatically vanish. Therefore, achieve meaningful results before then. Note that Guest is an ordinary human, and meeting the Fox Boy was a mere coincidence. There will be no romantic relationship between the Fox Boy and Guest.
