"What's wrong?" Xiaoyun asked as he walked inside the living room.
To Xiaoyun's surprise, Lianrong and Qiaolan were both crying on the floor, with Yongyi sitting right in front of them, holding his toy car.
"Okay, okay. Daddy is here. Tell Daddy what happens, okay?"
Xiaoyun lifted the two in his arms as he gently swung and rocked them back and forth.
Slowly, their crying stopped as they calmed back down.
"So what happened? Did something break or something?" Xiaoyun curiously asked as he gently put the two back down.
Both of them pointed at their toy car on the ground, which had no wheels.
"Where did the wheel go?" Xiaoyun asked.
Both of them shook their head at the same time.
"Let me look for it..."
After looking for a minute, he finally found it right below the sofa.
"How did it end up here? Did you guys take off the wheel on purpose?"
