CEO's mistaken lover

Cathy wakes up to discover she has spent the night with Lester, the CEO who is about to become her boss. Fearing she will lose the job before it even begins, she goes out of her way to slip past him, keeping her distance wherever their paths might cross. What she cannot see is that Lester believed he was with her sister Vivian all along. As their work forces them into frequent contact, a growing and lingering familiarity starts to build between them, and the question of when he will realize the truth hangs over every meeting.
