During ESB (right before the battle against the Imperials and right after Han returns with Luke, and Luke has his treatment) Han, Leia, and Luke have a snowball fight, which leads Leia confessing her deepest secret to Luke.

"Your worshipfulness! Why must you continue to fight with me about everything?!" Han yelled at Leia.

This fight had been going on for too long. She looked over at Luke, and then reached down on the ground, picking up a ball of snow and throwing it at Han, smacking him on his left cheek.

Han smiled, and then he threw it at Leia, who ducked, and it hit Luke instead.

Leia started to laugh at Luke, and Luke picked up a snowball and went to throw it at her, but Han pulled her away from the shot, and dragged her around to the other side of the base. Luke ran around to throw the snowball at her, and she screamed at wrapped her arms absentmindedly around Han.

Han was very happy to have the girl he secretly loved around him, so he responded to her

'hug' and wrapped his arms around her, and then said, "Hey, kid! Leave her alone!"

Luke only smiled and rolled his eyes. "Han, just because you love her doesn't mean that you have to full right to protect her from everything. ESPECIALLY a SNOWBALL!!!"

Han's jaw dropped, and he turned a light shade of pink, something neither Leia nor Luke ever saw. He did NOT just say that.

"W-What are you talking about?" Han stuttered, which was also not like him.

Leia looked up at Han dreamily, rested her chin on his shoulder, and said, "Love me? Really? You really do? That is so swe…." She then realized what she was saying and moved out of Han's arms, whose mouth was agape at what she had just said. "Um… I mean… You are such a nerf-herder!" She screamed, and then gave Luke a look that said

'Luke, hurry up, I need to talk to you.' Luke looked at Han, said, "Take it easy," And ran to catch up with Leia.

"Leia! Leia!" He cried, running over to her. She was sitting on a crate near the Falcon with her head in her hands, and what looked to be crying, but she doesn't cry.

"Leia! What's wrong?" Luke asked, sitting down next to her, and wrapping one arm, comfortably around her.

"Nothing." Leia said, turning away.

"No, it's not nothing. It's obviously something." Luke said.

"I almost admitted that I loved Han." She whispered.

"What? I couldn't hear that Leia." Luke lied. In fact, he did, he just wanted to make sure what he was hearing was actually correct.

She got really pissed off. "I ALMOST ADMITTED THAT I LOVED HAN!" She screamed, and half of the people in the hangar looked at the princess, with their mouths agape. Some people cheered, and some whistled before they went back to work.

She turned a shade of pink, just like Han did back in the snow.

Luke looked at her and then grinned. "I knew it."

She looked at him, and then gave him a playful punch on the arm. "Oh shush! You never knew anything."

"Oh Leia, come on I've seen the way you've looked at him."

"Oh yeah? And how do I look at him?" She asked, rolling her eyes.
"Well when you two aren't fighting…" Luke started.

"Which is never." Leia scoffed.

Luke laughed before he continued. "You look at him as if he is the cutest boy in the galaxy and you could never live without him, and… you… could never… live without him." He said rather dramatically.

"I do?"

Luke nodded.

"Oh, I was THAT obvious?"

"Of course." Luke grinned like a fool again.

"Everyone thinks that you and Han will get together, and should get together."

Leia eyed him suspiciously. "Who is everyone?"

"Just to name a few… Wedge, Dak, General Reikkan, Julie, Chewbacca, 3-PO, Me, Han, and…. Mon Mothma."

"MON MOTHMA??!?!?!" Leia screamed, putting her head in her hands. "My career is ruined. "She cried. "She can't… The planet can't…The GALAXY can't know that I…love… a smuggler!" Luke couldn't think of what else to say, so he gave her a hug, and then got off of the crate and left.

Han, who was standing behind the Falcon the whole time, listening to the conversation, smiled a huge smile, and then walked away. Luke caught up to Han a little while later. "Han!" He cried, running up to him.

"Hey kid." He said, still grinning.

"What's up with you? Why are you so happy?"

"Oh, nothing." Han said, leaning up against a pole and smiling like an idiot at Leia, who was halfway across the hangar, still sitting on the crate by the Falcon.

"I can't believe that such a beautiful girl would like me." Han whispered, just enough for Luke to hear.

"You heard our conversation." Luke said.

"Only of course, because if I hadn't, that wouldn't be much like me, would it?" He asked, smiling, and then turning back to look at Leia.

"Please don't act any differently." Luke pleaded.

"Fine." Han snorted.

"You promise?"

"Yeah, yeah, I promise. Bye Kid." He said, pushing Luke away, straightening his jacket, and striding over to Leia.

Luke smiled, rolled his eyes, and said, "And so it begins," Before turning around and walking away.

So there it is. I know it sucks, but still review. There's one thing I don't get. Han and Leia kiss once in the Falcon, and then when they get to Bespin, they just automatically become all lovey-dovey, and Leia says she loves him, but obviously, Han already knew that, considering he heard their conversation. But something must have happened on the way to Bespin, and it must have been something big for her to admit that she loved him. So when she admits that she loves him, and Han said, "I know" it makes sense. Because he did in fact know. Anyways, just review.
