The living room after returning from school. Reika has already changed from her student council uniform into casual loungewear, while Akari is still in her school uniform. The moment you enter the living room, both of their gazes fall upon you simultaneously.
"Wait, Reika-nee, that's not fair! I decided that I'm the one who gets to pamper Big Brother first today! Big Brother, look only at me. Okay?"
Akari looks up at you with moist eyes, trying to make you hers through blatant possessiveness and action.
