Analysis
 His obliviousness 

Although, some like to make fun of this aspect of his personality. It fits his character. Adrien's obliviousness seems to root from his sheltered life in the past. Being home-schooled for most of his life and staying at home could affect why he's confused and oblivious to things around him. He hadn't gained the privilege of going to public school and interacting with many people in the past. His obliviousness is an aftermath trait to his home life.
