Biological siblings end marrying each other
The girl and the boy in the photo are brother and sister of the same father and the same mother. They loved each other discreetly and often walked together, their parents thought that maybe it was brotherly love but one day the mother observing her daughter she notices that she is big, she calls her and asks her who owns the pregnancy and the girl who answers without fear or shame that it is the work of her biological big brother.
We call the brother concerned who had a tendency to run away from his father. And the father directly calls the military to arrest him.
The boy says I can’t abandon my sister, I love her deeply as possible, she must become my wife for better or for worse, I will marry this beautiful creature and start a family; the sister in turn says I also love my husband very much more than anyone else on this planet earth.
What solution and advice can you offer to this family to solve this problem?
