You didn't see us alone in the south passage. She expressed her true feelings for me. - Han Solo / Star Wars: The Empire Strikes Back
Han Solo may just be a scruffy-looking nerfherder in a hooded brown jacket, but in matters of love, he knows the truth about Princess-turned-Rebel-leader, Leia Organa, and the affection she holds for him. Or so he thinks.
In the icy south passage of the Rebel Alliance's Echo Base on Hoth, the two allegedly exchanged-warm words confessing their feelings for one another. However, when Solo mentions this to Chewbacca and Luke Skywalker, Leia brushes him off and kisses Luke to prove that the so-called feelings she shared are nothing but bantha fodder.
Still, as the battle against the Empire wages on, it becomes clear that Leia has a soft spot for scoundrels, and Han has his own true feelings for "her worshipfulness". While the two begin to earn their respective reputations as heroes for the Rebellion, they come to discover that sometimes in love, it's just about knowing.
