How… How much had he heard?
Su Yi had always thought that she had been trained to be very calm after the past few years. Although she was trying her best to suppress her emotions at this moment, she still wanted to quickly burrow into a hole in the ground and hide!

"I went to buy something." Lu Yubai let out a low cough to hide his embarrassment. He took a look at Cheng Ye and quickly changed the subject. "Xiao Ye is here."
Cheng Ye stood up politely to help him carry the things and greeted, "Hello, Teacher Lu."
Then, he stole a look at Su Yi. Teacher Lu seemed to have heard everything. Sister Su Yi's face was as red as a cooked prawn.
