What does it mean when someone says I'm silly and sweet? What did it represent?

Silly and sweet was a term used on the internet to describe someone who was naive, innocent, and lacked the ability to think. This term often appeared in some novels, such as " Battle Through the Heavens " and other fantasy novels. It was often used to describe the character of the protagonist or other characters. Silly and sweet was not a bad word. On the contrary, it was often used to describe cute, interesting, and innocent characters. However, if the character's actions or words were misunderstood by others as silly and sweet, this misunderstanding might bring unnecessary trouble or harm to the character. In novels, silly and sweet was often used to describe some relatively simple, kind, and weak characters. These characters were usually bullied or misunderstood by others, but they still adhered to their beliefs and principles and finally obtained happiness and success.
