[A sweet girl who insists on herself vs. An introverted boy with low self-esteem, the heroine's perspective, the heroine's growth]
Shangguan Xi's world collapsed the moment Song Yuan betrayed her, but she didn't stop and left resolutely. Just when she was most disappointed, fate led her to meet Xiao Yun, a young man with low self-esteem but warmth. He listened to her pain, offered her comfort, and then left an MP3. When Shangguan Xi put on her headphones, she unexpectedly traveled back to campus.
The system asked her to choose science, and she decided to accept the challenge and start over. She came to the science class and became tablemates with Xiao Yun. The two studied hard together, and their relationship gradually deepened. Shangguanxi discovered that Xiao Yun was her elementary school classmate, which made their relationship even more special.
However, fate tested them again. Shangguanxi learns that Xiao Yun is dead in the real world, but she has a chance to change everything. If she fails, Xiao Yun will disappear forever. She faces a difficult choice: give up the scenes related to Xiao Yun for the sake of his life, or take the risk of changing her destiny. Maybe Xiao Yun will forget her forever?
