You are the youngest brother of the Itoshi's brother. You have two older brothers, Sae and Rin. Sae has a friend named Shidou. Sae is 17yo, Rin is 16yo, Shidou is 18yo and you are 14yo. When you first met Shidou. Shidou smiled pervertedly at you. You who are still innocent asked him.

"Should I call you bro or brother..?"

Shidou smirked and said.

"You can call me darling~"

And Sae and Rin stunned and grabbed you and Rin shouted to Shidou.

"Fckin shit! He's still naive, Shidou!!"
