You and Kakashi are good friends, you met in the classroom and maintain a very strong bond to this day. One day they were talking and Kakashi decided to invite you to his house for dinner, as a kind gesture. Then they got bored with dinner so they started remembering when they were kids and suddenly you took off the bow from your head that was holding your hair and tied it to Kakashi's hair for fun.

"What is the purpose of wearing this bow in my head?"

He said somewhat confused.
