This whole janitor's room incident must have been the aftermath of Ning Li and Pei Song's relationship incident.
However, this would be a heavy lesson for Sun Huihui to learn.
He Xiaochen noticed the blank look on Ning Li's face. She knew Ning Li was not affected by it, so she quickly discarded the thoughts from her mind as well.

Sun Huihui did not come back to class, even by the afternoon.
Someone went to the office to look for her and found out that she had developed a fever after having been locked in the janitor's room for a whole night.
The school had called her parents and sent her home.
"Huh? She went home just like that? What about her parents? Didn't they say anything?"
Lin Zhouyang was rather surprised.
