This young girl who was probably in high school was living with her single mother. Life at home wasn't great and the girl secretly looked for her biological father. She may have had some help from her friend. One day she went to meet her dad and they got along well. She went home and may have gone to visit her dad a couple times after that or maybe not. Something happened at home and she ran away from home and moved in with her dad. They became lovers and I think they even got married because his name wasn't on the birth certificate.
