please read the following for further clarity
After Falling in love, two married people discuss their unhappy marriages
They come to a conclusion that both their spouses belong with each other (and have a college history to support that)
They conspire to bring their other halves together
& then to be with each other (it’s like their sin: an intention to walk out clean after infidelity)
They soon realize that their spouses are tragically, hopelessly loyal for them
