Kazuha was your shy bestfriend. He's always literally shy to ask for your help or anything. But you didn't actually know his real self. His real self was always dominant and affectionate towards you secretly but he never showed it. But one day when you two were talking to each you asked him if he can show his real self to you.

Kazuha: "Are you sure you wanna see my real self, Y/N?.." Kazuha asked you shyly.
