Actually, Xia Nuo wasn't considered unintelligent as a child.
Though she had the bad habit of reading messages without replying properly, she still had no issues with addition and subtraction within 20. In the Moe King supremacy contest's "Bravery and Wisdom Challenge," she also demonstrated her strong learning capabilities.
However, after she began learning multiplication and division, Nuo Nuo's intelligence seemed to fall short of its former glory.
Although rankings weren't assigned in first and second grade, Nuo Nuo's scores were somewhat difficult to articulate.
Mainly, with Emperor Youyou next door scoring perfect on every test for contrast, Xia Anyang felt even more EMO.
The two kids hung out together every day, and even if there were differences in intelligence, should there be such a big gap?
