Harry and Ginny
Reasoning: This card represents the obvious interpretation of romantic relationships, intimate union, desire and physical attraction. It also represents all relationships and connections, and also finding out what is important to you, what you value, and making a moral or ethical choice. It can also mean struggling with temptation and making the right choice, which Harry struggles with when his relationship with Ginny first begins and he must make the tough decision to stop seeing her for her own protection... an act of love. Fortunately, this turns out to only need to be a temporary hiatus, for eventually these two teenage sweethearts end up married and starting a family of their own. Awww....
In a traditional tarot deck, this is the Lovers.
Notes
I knocked this card out in one day, which is a little unusual for me. I just knew how I wanted it to look, and it just fell into place nicely. Ginny's face gave me trouble for a while, but in the end I think it worked out OK. This is after the Gryffindor Quiddich victory in Harry's 6th year, the celebration of which culminated in him and Ginny running and kissing one another, which marks the start of their romantic relationship.
