A Lovely Farewell

Winds were soft and temperatures escalated with the growing tension in the air in the hottest season of the earth's rotation.
The tension was that of a forbidden lust, an unconquered fear of falling in love. How easy and nice it was to fall in love, but how quick and heartless it was to fall out of love.
Two canines, located in a forest near Denver, were going through the "falling in and out of true love" phase. However, they never truly fell out of love. Only a border that couldn't be broken stood between the two young canines.
She left with no goodbye. No warning. He had to find out the hard way, and would soon fall into a deep and heart wrenching depression. His current mate, despite the heartbreak she also has experienced, would help him to find the lass who had left with no goodbye, just so he could receive that final goodbye.
Would they reach their destination? Or would unexpected encounters bring the duo to a halt?
