Seeing An Hao didn't intend to elaborate on the situation, Lei Linxuan felt embarrassed to ask further.
However, being in the same research group, not greeting the teacher would still be improper.
Moreover, Teacher Cheng had always been kind to her. Although not as enthusiastic as with An Hao before, each time she sought help, Teacher Cheng gave the assistance she promised without fail.
"Since it's like that, then go ahead," Lei Linxuan said to An Hao. "I'll give Teacher Chen a shout, and then I'll be up shortly after."
So An Hao went upstairs, and Lei Linxuan hurried over to greet Cheng Yu, "Teacher Cheng! You've finally returned! We heard you were sick and wouldn't be back for half a year; we've all been very upset."
Cheng Yu revealed her signature smile, "One step on campus and I get to hear such heartwarming words, I'm very happy."
"I'm speaking the truth," Lei Linxuan patted her own chest, "In my heart, Teacher Chen, you are a goddess!"
"Thank you for your compliment."
