Despite a strong attraction, Greg and Fiona spend two years apart because of two wrong assumptions on Greg's part. During those two years, Greg renovates and moves into his grandmother's house, acquires a dog, becomes a Big Brother to six-year-old Tyler, and then adopts the boy after his mother dies. Fiona takes a sabbatical, sublets her apartment, moves in with her mother, and completes her Ph.D. Both Fiona and Greg try dating others without success and rely heavily on family and friends until a chance meeting in a park brings them together again, this time happily and without assumptions. After two eventful years of trying to forget each other, they discover that the only thing that hasn't changed about them is their love for each other.
