Meng Fan introduced her, "Wu Tong, she's my classmate."
"Classmate?"
Bai Zhi gave Meng Fan an accusing glare, seeing through his deceit, but did not continue to ask.
Su Qing Cen was not familiar with Meng Fan, but Bai Zhi was. At least, familiar enough to know that Meng Fan was too low-key to bring an ordinary classmate to the backstage of a concert. She knew Meng Fan didn't want people to know his status, as Meng Cai Wei's younger brother was afraid that it would cause some trouble.
Maybe they really were classmates for now, and maybe they would only be classmates in the future, but Bai Zhi was 100% certain that Meng Fan wanted to take their relationship one step beyond just classmates, and maybe even several steps.
