This is the story of cousin's, they were born on the same day and were really cute. Their parents named them sapphire and gold , gold for the boy and sapphire for the girl; kind of strange,right?.
The thing about this two was that they were the only children of their parents so,the two family's decided to make them grow up like siblings,just so they won't feel alone. So they bought them similar things so they would look more like twins.
And every weekend gold's parents would come to sapphire's parents house so their children would be fond of each other, and they planned to do this interchangeably;like this weekend gold's parents would come to sapphire's parents house,next weekend sapphire's parents would come to gold's parents house.
In doing this, their children grew and did everything together, but there was one thing their parents forgot to tell them as they grew, they didn't tell them that they were related.
