Xu Nianhua looked at him with a complicated expression and said, "Second Brother, if I told you that I've forgotten all the ancient poetry, as well as the formulas in math and science, would you believe me?"
"Pfft~"
Xu Nian'an immediately burst out laughing.
At this moment, they were walking from the cafeteria back to the classroom, with quite a few people around. Xu Nian'an's laughter drew everyone's attention.
Xu Nian'an cleared his throat and explained, "I was telling my sister a joke."
After explaining, Xu Nian'an pulled Xu Nianhua to the side, under a tree, and said, "Little Sis, that joke isn't funny at all."
Xu Nianhua pressed her lips together and stayed silent. Her bright, clear eyes looked at Xu Nian'an with a serious expression.
Suddenly, Xu Nian'an realized that what she just said might not have been a joke at all.
