In her past life, Xu Liming was a simp, pursuing Lin Wan for six years. Not only did Lin Wan steal her work and win an award, but she also cheated on her on her birthday, sleeping with her rival. The night she learned the truth, Xu Liming was disoriented and accidentally drove her car off a cliff, ultimately dying at the age of 25. When she opened her eyes again, she was back in her nineteen-year-old classroom, confessing her love to Lin Wan in front of the entire class.
