Kathleen is Laurenti\'s first love. However, Laurenti was a well-known womanizer that makes Kathleen afraid to fall in love with him. Her priority is to finish her studies to help her father run their advertising company.
One day, Laurenti asked Kathleen to pretend as his girlfriend to drive away women who was chasing him – which was a total lie. In return, Laurenti will help her pass her Calculus subject and make sure she’ll graduate in college. Kathleen agreed because she badly needs her diploma. Few weeks passed, Kathleen has fallen in love with Laurenti.
Before she could confess her feelings however, Laurenti disappeared without any word. On Kathleen\'s graduation day, he took a flight to San Francisco, California.
Two years later, Laurenti came back to break Kathleen\'s heart again. He was about to marry Kathleen\'s cousin, Donna.
