In her previous life, Song Jinyue was too softhearted. She took her seriously ill roommate, Wu Ya, to the hospital where her older brother worked to get her treated. But Wu Ya turned around and falsely accused him, claiming, "He sexually assaulted me." Her brother was fired, her parents couldn't survive the devastating online harassment, and Song Jinyue herself was locked inside the dormitory and beaten to death. When she opened her eyes again, she had returned to her freshman year of college. Beside her was the very same bag she had prepared to take Wu Ya out. This time, she put it back on the table. Wu Ya continued showing off her so-called feminine charm, flaunting her relationship with Li Chengze, secretly hiding a camera inside a plush teddy bear, posting photos on Tieba, and selectively editing their chat records. Song Jinyue neither persuaded her, argued with her, nor offered explanations. She simply collected the evidence, one piece at a time.
