For Sakura, meeting her classmate Hiroshi marked the beginning of her first relationship. Opening her heart to him little by little, she approached him with pure, honest feelings. However, still young and overwhelmed by passion, Hiroshi began pressing her for more. Though Sakura's heart fluttered at his intense affection, she wasn't emotionally ready and continued to reject his advances. One day, on her way home from school, Sakura was suddenly stopped by a suspicious man. Feeling uneasy about his demeanor, she tried to run, but was easily captured. Dragged into an abandoned house, the pure heart she had carefully protected was brutally shattered. From that moment on, Sakura's life would never be the same.
