The Love Letter explores just how tricky things can get when your best friend is the opposite sex. Parker (Keshia Knight Pulliam), an established entertainment columnist, and her sports-fanatic best friend, Aaron (Romeo Miller), have been inseparable since childhood. They know everything about each other - from her dating mishaps to the fact that he doesn't love his current girlfriend, which makes his sudden engagement all the more surprising and planning his wedding very difficult. Parker's meddling mother, Josephine (Jackée Harry), is determined to get her mind off of Aaron's wedding by introducing her to "nice guys," including millionaire Wesley (Marques Houston). Still, Parker finds it impossible to focus on much besides Aaron and his relationship. She decides to explore her feelings in her magazine column, penning a letter from an "anonymous" reader looking for advice. Surprised by the overwhelming reader feedback and her feelings, Parker realizes something about herself and what she really wants out of life.
