Ever since she was a child, whenever her family visited the countryside, "Fumika" would quietly whisper with affection and admiration, "I'm going to marry Uncle." Unaware of her pure feelings, her uncle, though seeing her as just a kid, found himself increasingly drawn to his niece's growing beauty each time she visited—secretly indulging in mischievous acts behind her parents' backs. Fumika, too, gradually became entangled in his actions, quietly harboring her own deepening emotions. When she was finally allowed to visit the countryside alone for the first time due to her schooling, she headed toward that house, ready to embrace a new, forbidden intimacy with her uncle—away from prying eyes.
