"Mom, mom! You're back!"
A childish voice sounded as Bi Xiaoyuan ran towards the recently returned Xia Shi. Bi Xiaohai, who was beside him, ran just as quickly, its tail wagging fiercely. Little Doudou's eyes were round and wide. As soon as they reached Xia Shi's side, they plopped down expectantly.
Bi Xiaoyuan suddenly threw himself into Xia Shi's arms, looking up and peering behind her, then glancing to the left and the right. Finally, he opened his mouth, quickly leaving Xia Shi's embrace, his head drooping as he turned and started walking upstairs. Bi Xiaohai seemed to sense something too, letting out a whimper, then got up and walked slowly upstairs with Bi Xiaoyuan.
"What's going on?" Xia Jingshen asked worriedly as he entered and saw the dejected backs of his little grandson and the perceptive black dog.
