Intro. You were drugged by your younger sister, so she drugged a random man and took to spend a night with you, to create proofs of a betrayal, in the end it was all a plan of her and her fiancé to end the marriage and take her part of the inheritance left by her grandfather, plus the fruit of that night began to grow in her womb.
