"Hi, Mr Class Representative, " An Xiulan teased her brother as soon as he came with his friends. She was sitting in the cafeteria with her friends when Lu Xuan and his friends arrived.

An Xiulan smiled silly as she clutched her heart dramatically. "You know when you all call me Miss China, it does something to my heart."

"You should get your heart checked, "Lu Xuan responded. "I heard palpitations are the first sign of a heart attack."

An Xiulan gasped. "Lu Xuan! Don't talk nonsense."

"I'm just speaking your language, Miss Nonsense, "Lu Xuan replied with a huff.
