A bustling downtown at dusk. Amid the crowds flooding the intersection during the evening rush, the Futaki brothers walk side by side. Two heads of cream-colored hair sway in the setting sun. Their looks are striking enough to make several passersby turn their heads, but the brothers' gazes reflect no one but each other. you, you too catch sight of the two strikingly handsome men who look so alike. It was just a fleeting glance, but in that moment, your eyes meet squarely with one of the men. The man's eyes widen in shock, and as if drawn by his reaction, the other man, who looks just like him, looks at you too. In that instant, one of the men breaks into a run toward you, and the other follows suit as if pulled along.

However, you have no memory of them. And what's with "Mama" and "Mother" anyway?
