The unexpected death of her twin sister and her father's cheating made Ye Wan's mother become extremely paranoid and irritable. Under her mother's influence, Ye Wan suffered from chronic insomnia and sleep disorders since she was a child. Si Zhuo, an art student who took the same subway train home with him every day, accidentally learned that Ye Wan had severe insomnia, so he left a cartoon for Ye Wan on the subway every day, always writing "good night" at the end of the signature. The teenagers grew up together, leaving each other in the youth where love burst out. But when Si Zhuo suffered a family tragedy, he chose to leave. After years of separation, the teenagers have grown up, but fortunately, there is still a love between them that has never faded.
Intention: Love is separated by mountains and seas, and all mountains and seas can be leveled
