Su Jingying has two faces: during the day, she is an inconspicuous and well-behaved academic, but at night, she expresses all the truth with graffiti on the abandoned rooftop.
When her most secret self was exposed by Jiang Shubai, the god of learning that the whole school looked up to, he picked up the diary she had left behind. He made no threats and only made a strange request: "Sit with me for two hours a week, and I will keep it secret for you forever."
From then on, the two pretenders began a silent contract in the corner of the library. She writes poetry, while he suffers from insomnia; she pretends to be meek, but he plays it perfectly. Until rumors spread and the past was revealed, he tore up the model test paper in public and held her trembling hand:
"When you're tired of pretending, just be yourself."
"The sky is falling, I'm taller than you."
This is a story about two imperfect souls who find the courage in each other's eyes to not have to pretend. He cures her fear, and she cures his insomnia - the sweetest candy, wrapped in the truest self.
