Talks about Two sister one of them don’t like the the other sister and she drugged her and put her in a room with a man was waiting for someone i guess and she slept with him and then she had twins but then the doc tricked her and told her that she got just one baby and her sis took the other kid to the man and told him that he slept with her and forced him to marry her but after some time the two kids met and switched with each other to try to reunite their parents again
That’s how I remember it
