When he loves her, she is his whole world. When he no longer loves her, she isn't worth a damn!
Who says love is something one person can have alone? That's unrequited love, not love! He has an irreplaceable first love in his heart, and she has a childhood sweetheart who could do anything. His first love married someone else, and her childhood sweetheart did too. So two people, both scarred by love, meet, come to know each other, and torment each other. Will their makeshift love finally lead to a happy ending, or will one of them remain merely a substitute? Love and hate are bubbles... one touch, and they burst.
