Zhao Lin put down her pen and walked over. "What happened?"
Seeing this, Yu Yan immediately replied, "It's fine, Director Zhao. I took the wrong letter."
Yu Bing stared into Yu Yan's eyes and revealed a faint smile. "Do you think it's fine to yell at me after you took the wrong letter? I saw that you looked so emotional when you took my letter. I was frightened since I thought you were going to take my letter away."
When Yu Yan's thoughts were exposed, she immediately retorted, "Who said I took your letter?! Stop slandering me!"
Yu Bing tilted her head and looked at Yu Yan with a frown as she said, "I didn't slander you. I just said I thought you were going to take my letter away with me. Moreover, you did take the wrong letter and shout at me."
The letter box was placed on the table beside Zhao Lin's desk. She usually kept it. When she took it out at work, she would lock it back in the cabinet after leaving the office.
