Telling Zhou Mochen to wait downstairs, Xu Su went up to the second floor alone.
At the door of Sophomore Class 3, Xu Su pushed the door open and peeked her head inside.
The teacher giving the lecture looked at her questioningly. Xu Su's gaze swept across the classroom, and after spotting Chen Ni in the middle, she explained her purpose to the teacher.
Only then did Chen Ni realize it was Xu Su. After getting the teacher's permission, she stood up joyfully and walked out of the classroom.
"Susu, why are you wearing a mask like a celebrity? I almost didn't recognize you." Chen Ni threw her arms around Xu Su and, while talking, pulled her mask straight down.
"It's just more convenient this way." Xu Su pushed her hand away and pulled the mask back up properly. "You're a sophomore now. How are your grades?"
