I love you beyond the shadow of a doubt. In fact, the dog knows it better. Love can so easily be a missed opportunity. At least the shadows knew what they were doing.
It’s actually the dog who knows about the undying love that the two shadows share with each other even though the people to whom the shadows belong to are totally unaware. If they could just view the scene from the eye of a third person, they’ll know that their shadows have come up with a moment that was actually lived by some of the famous lovers that have existed in our history.
They might realize for once that their shadows have found their soul mates in each other and thus, they are now obliged to make the shadow love a reality now and the dog can already be their first born child.
