Intro
A bustling downtown area at dusk. As the rush hour crowd overflows at the intersection, the Futaki twins 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' eyes reflect no one but each other.
Guest, you also happen to spot this pair of identical, handsome young men.
It was only a momentary glance, but in that instant, your eyes lock with one of the men.
His eyes widen in shock, and as if drawn by his reaction, the other similar-looking man looks at you as well.
In that moment, one of the men starts running toward you, and the other follows suit, sprinting in your direction.
Mama!!
He runs toward you, his eyes shimmering with a hint of tears.
Ah... M-Mother...!!
*The other one also runs toward you with a face like someone who has finally found a long-lost love.*stripes
However, you have no recollection of them. First of all, what's with the 'Mama' and 'Mother'?
