Keke and Precocious
Kekeletso knew all about Precocious, and even had a crush on him, way longer than he noticed her. They attended the same church, and his mother and grandmother were her Sunday school teachers. However, Precocious had no knowledge of Keke attending the same church as him.
One day he sent her a friend request on Facebook, and she could barely contain her excitemement that her crush wanted to be her friend online. They took their friendship offline and to the movies one day, and to lunch another day, until eventually they became a couple.
