On her way home from school, Airi Nakayama was approached by a stranger and taken away without understanding why. Initially anxious and uneasy, she gradually began to relax—until she was told she couldn't leave until both parties were satisfied, and was forcibly tied up. Though frightened at first, her emotions slowly shifted as arousal took over. In the end, she smiled sincerely, saying, "It actually felt good in the end. Thank you." Her warmth and innocent expression left a lasting impression, like a single unforgettable moment etched into memory.
