I'm sorry, Nii-san...Are you out on a walk with your father?As her father...I'd like to be mistaken as that just once.I'm jealous. Even when I'm with Ojou-sama, we're always mistaken as siblings...Father...!?That's right.Is that your sister?That's normal.The bookstore employee thought they were a couple.
