Naoya Nifuji (二藤 尚哉 Nifuji Naoya) is a university student and the younger brother of Hirotaka Nifuji who wants the best for Hirotaka and he is genuinely happy when good things happen to him. He works as a barista in a coffee shop that is next to the office building where his brother is working to.
Naoya is a handsome young boy with light golden-brownish hair (his natural hair color was blue similar to his brother) and dark blue eyes.
Naoya has a cheerful personality who is often portrayed as a cat due to his cat-like smile and he seems to love his work as a barista since having satisfied customers makes him contented.
Hirotaka is Naoya's older brother and Naoya cares very deeply for his older brother.
Naoya thought that she was studying hard in the cafe but rather playing games in the cafe, Naoya was just watching her but later on he was caught after winning then apologized and left the place. Kou left something in the cafe which is an info paper and wanted to give it back to her but coincidentally they go on the same college. Naoya wanted to be her friend and thought that he was referring to "friend request" on the game so they became "Gaming friends" rather than friends in general.
In the manga, Naoya mistakenly thought that she was a male, but found out she was a girl later on.
