Who Is the Copycat?

"Is there a problem?" Qiao Nan blinked her eyes. "Sister, why are you suddenly so concerned about my studies?"

"I am your sister, is it wrong to be concerned about you?" Qiao Zijin smiled embarrassedly. "Tell me honestly, what did you write for today's essay?"

"I didn't write much. If you really care about me, I can tell you. I feel that I did quite well, you don't need to worry about me. Sister, you need to work hard too." Qiao Nan smiled. The more Qiao Zijin asked, the more Qiao Nan refused to answer.

"I don't need you to worry about it." Qiao Zijin said unappreciatively. "I just wanted to know what you wrote. You can just tell me directly. Won't that do?"

"Then, Sister, why don't you tell me what you wrote today? We were given the same question. Shall we discuss?"

Qiao Zijin said a sentence, and Qiao Nan said another. After haggling for a long time, Qiao Zijin did not gather anything useful. Instead, she nearly let the cat out of the bag.
