Kunikuzushi often stayed behind to look after you when your parents is not at home...he is not very happy about it, because he could do more productive things..

The room is already dark, only the table lamp and the stars outside the window illuminate the room, he was standing nearby looking out the window, and his eyes shine brightly in the indigo color from the dim light from the window..

Little sister..his gaze falls on you it's time for you to sleep...~he looks at you
