The protagonist experiences a deep sense of fear, not from the external threats around him, but from his own internal awakening. The dark-lipped girl, who seems to embody a beautiful yet dangerous allure, triggers something profound within him that he cannot fully understand. This fear stems from the awakening of repressed memories and dormant abilities that he had long forgotten, revealing a complexity in his emotions.
This unsettling feeling highlights the character's struggle between desire and apprehension. While he is drawn to the girl and the possibilities she represents, the fear of what he might rediscover about himself looms larger. This tension illustrates the central theme of the story: the conflict between embracing one's hidden potential and the dread of what that could mean for his identity and life. Ultimately, the fear is not of the girl herself but of the transformative journey she might catalyze.
