A/N: Hey lovelies, I based this off of a beautiful piece of fanart I found on tumblr. Read and Review!

September 15, 1977

Lily was in the astronomy tower going over her star charts, periodically looking up at the sky or through the telescope positioned carefully at the edge.

The astronomy tower was one of her favorite places to be. It didn't have windows so you could lean out and enjoy the night air, and look at the stars. Tonight it was very fine weather, it had been warm during the day, but now that the sun was set it had grown cool and a slight breeze blew through the open walls.

"Hey, Evans." James called from the door.

"James I don't have time for your shenanigans, I need to finish this!" Lily replied, not even looking away from her chart.

"Careful Lils, you might spend all your time doing homework and forget to live." He smirked.

"Careful Potter, you might spend all your time goofing off and forget to learn something that will keep you off the streets." Lily smiled to herself, still not looking at him.

James was quiet for a moment, Lily took this as a victory and carried on working.

Finally curiosity overcame her and she looked up at him.

"James! You can't sit on the windowsill!" James had one leg hanging out of the tower and one bent and foot on the sill and he was leaning against the side casually and looking out over the grounds.

He turned at her voice and smirked, "Is that concern, Evans?"

"No," Lily stood up a little straighter and huffed, "Just… you are head boy, you have to set a good example!"

"Yeah, for what little first years? There's no one here, Evans." He smirked again, he seemed to do that a lot.

Lily turned back to her homework, studiously ignoring him. She could practically feel his smirk get bigger.

Lily finished her chart and began packing up.

"Hey Evans, if I jump out the window will you kiss me?" He was looking down at the ground and had a half smile playing on his lips.

"What? No, you would never jump, it's at least 60 meters!"

"But would you kiss me?" He looked up from the ground to peer at her behind his glasses.

"No, James I wouldn't kiss you that's such a dumb thing to do. I'm not going to reward dumb behavior."

"But, you just said that I would never jump, so it's a safe bet right?" He waggled his eyebrows at her and Lily rolled her eyes.

"Alright, Potter, since you'll never jump, fine, I'll kiss you-" she had said it sarcastically but then he had just slid off.

"Arresto Momentum!" Lily yelled whipping out her wand. Lily ran down the tower stairs and out onto the grounds where James was floating a meter off the ground trapped by her spell.

"Finito," She muttered quickly, he fell the meter onto his face. He stood quickly and wiped himself off. Lily was fuming.

She rushed at him and began screaming at how stupid he had been, but James just laughed.

"Why the bloody hell are you laughing!?" she raged.

"Well it's a bit funny-"

"There's nothing funny in jumping off the window just to earn a goddamn kiss!"

James smiled down at her, "I can't even handle how beautiful you are when you're angry, Evans." he whispered.

Lily huffed and folded her arms across her chest.

James began to walk away back towards the castle. "You owe me a kiss, Evans." He called softly.

The hairs on the back of Lily's neck stood up and her whole body felt strange.
