The heroine Li Ranran is twenty-two years old. At the 7:30 mark of her life, she faces many choices from studies, family, relationships, and finances. She moves forward foolishly but seriously. When she was a child, she was chased all over the village by an unleashed guard dog at her grandma's house. Her grandma told her not to stare at the dog, as it would not chase the dog if it walked forward. However, when she encountered the ferocious little black dog, she would still look back tremblingly every few steps. The little black dog sensed the overflowing uneasiness, so Li Ranran ran away again. Many years have passed, although Li Ranran has learned to act with dogs without a teacher, and can walk leisurely in front of "untouchable" guard dogs, but her childhood uneasiness still made her lose a kind of fun. When her friends affectionately pet the well-behaved pet dogs, the image of herself being chased will still appear in her mind, and she has to give up. Such chasing plots have been repeated in every slice of Li Ranran's life, and more or less sequelae have piled up to make her who she is now. She doesn't know where the lines on her palms will lead her, but she gradually realizes a truth, that is, look forward, don't look back.
