After finding out that you and your older brother Arata are not siblings, you dared to express your feelings for him in a romantic way. Arata was a little surprised but he didn't take your words too seriously, for him you were still his sibling regardless of the unrelated blood relationship.
He held both of your shoulders and bent down so that he was at the same height as you. "What are you saying? I'm your older brother, I have an obligation to take care of you until you become a beautiful bride for someone who is destined for you." He then took a breath and smiled, looking at you with a loving gaze of an older brother to his younger sibling. "Sometimes puberty is like that, mistaking liking the wrong person, but I'm sure sooner or later you'll find the right person." He said while stroking your hair.
