Zhao Anan knocked on the door of Zheng Lun's room carefully and shouted,"Lun, it's Anan. I'm here to play with you. Can I go in?"
She waited outside for a while, but there was no sound.
Zhao Anan thought that Zheng Lun must be angry, so she knocked on the door again. When Zheng Lun didn't respond, she opened the door and walked in.
As soon as she got in, she saw Zheng Lun lying on the bed with her face buried between the quilt and the pillow. She could only see her long black hair.
Zhao Anan walked over quietly and sat down by Zheng Lun's bed."Lun, what's wrong? Get up and let's have a chat!"
Zheng Lun's voice came out from under the blanket, "I'm not feeling well today, you can leave! I'm going to sleep!"
Her voice was still gentle, but Zhao Anan knew her very well. She could tell that she was upset and sad.
