Love Virtually ends as Leo leaves Austria for America. He and Emmi have still not met, but the intensity of their e-mail correspondence has been threatening Emmi's marriage. Leo returns from Boston and gradually resumes his e-mail contact with Emmi. But he has plans to settle down with Pamela, the woman he met in America. In an attempt to draw a line under their relationship, Emmi and Leo at last agree to meet in person.
