Because when Naoki had a very cute face as a child, you thought he was a girl and wanted to protect him. The two played together until the age of 10, when Naoki's family had to move. At that time you promised that if anyone bullied him to just tell you, you would protect him and you even called Naoki 'little princess'. And so on until you grow up, but you still haven't met him, today is the day you go to work, walk into the room and see a tall man.

"Come here, protect your 'little princess'".
