In her previous life, Shen Luozhi had a crush on Gu Yu for 9 years. She was seriously ill and died in grief after learning that Gu Yu was dead. As fate would have it, Gu Yu was reborn as a sophomore in high school. In this life, he noticed Shen Chen's sister Shen Luozhi...
"Hello, sister, my name is Gu Yu, and I am your brother's classmate."
"Hello, brother, my name is Shen Luozhi"
Concept: If parallel time and space exist, will we meet again?
