Obviously, the Lovers is a card that usually embodies intimate physical and emotional love. It encourages harmony and union within relationships. However, this card can also represent difficult moral or ethical value choices - such as those often brought about by a complicated relationship - where one must decide between two paths by following his heart.
After years of misdirected attention, Harry comes to realize that Ginny is the girl with whom his heart truly lies. However, he is conflicted by his dangerous mission, fearing that it would place Ginny at risk. Despite Harry's concerns, though, Ginny continues to fight for his efforts from afar, proving herself a courageous and strong partner well-matched for Harry's heroic responsibilities.
At first glance, this card looks merely sappy, but it actually depicts the (liberties taken) scene where Harry decides that he must break up with Ginny. The faint phoenix of smoke comes from Dumbledore's funeral pyre, as a symbolic reminder to Harry about the mission that weighs over his head. Even so, the strength of their affection for each other is still evident in the ivy (loyalty) and oak (strength), as well as the tiny forget-me-not Ginny wears in her hair.
