Didi is a woman living in the 21st century who knows what she wants and pursues it to the end. She had big dreams; get married, get a good paying job, and maybe have kids in a big house. But her family did not care about all that after they found out that she did not stay true and pure before her wedding day. It got so bad that they even forced her husband to be to turn her down at the alter. That is how you fund her.
