Rumors spread around the campus. It was said that there was a secret on the first floor of the school. This aroused Meng Hui's curiosity and dragged Shi Xun to explore the secret in order to solve the mystery.
But after entering the closed archives, things got out of control step by step. Meng Hui became "transparent" step by step, and was slowly forgotten by everyone, and even disappeared completely in the end. After the cycle, he was replaced by Zhang Yuan.
Concept: The male and female protagonists grow up in difficulties, help each other, and have a spirit of unity.
