Ainun and Aida were two teenage girls who lived in Desa Sempalang, north Sulawesi. From the time they were children, the two were inseparable. As fate would have it, they were born on the same day and so both Ainun's mother and Aida's mother thought it would be fitting to give their daughters very similar names. They agreed to name one baby Ainun and the other Aida. Although they were not sisters by blood, they had several things in common. They were both tall, slender and beautiful. Ainun was left without a mother. She had died when Ainun was nine years old. Meanwhile, Aida's father had died when she was just seven.
