He saw how naughty and tough Xue Shi was acting and laughed.
Xue Erhu and Yu Hongyan sized up Jiang Yue, Xue Yan, and Sifu for a long time. Seeing that there were no changes, they smiled happily and said, "It's good that nothing happened to you. If you lose weight or something bad happens, you won't be able to explain yourself to us, let alone your family."
Seeing that Xue Shi was sticking to Xue Yan and Jiang Yue again, they smiled and said, "He was fine when you guys left, but after that, he kept crying when you guys were nowhere to be seen. He was so sad that he kept babbling. He just kept dragging his family members to your room and calling your names because he missed you guys. Especially these few days, he cried so much that we had to coax him to come out and look for you guys. Only then did he stop crying. Now that he has seen you guys, there's no need to bring him out anymore. Look at how happy he is. It's like he's stuck to you like glue."
