Gugu & Sipho
Sipho and Gugu had always known each other, having fellowshipped at the same church, but they had hardly noticed each other; until they were both in a wedding party. Sipho was one of the groomsmen and Gugu was a bridesmaid, and they were forced to work closely with each other, and a spark was ignited.
After the wedding, Sipho asked Gugu on a date, to which she retorted, "What is a date?" Eventually, she agreed, and they've been inseparable since.
