A/N: Another series for me! I know the idea isn't that original, but I'm going to make it my own, don't worry! Well, this is pretty much going along the lines that Lily is an impossible, perfect monster and James thinks he can tame her. He has one year to do so, and the year is going to be filled with love, lust, hate, and good ol' misadventures all around. The story starts halfway through September of their Fifth Year. Enjoy!

"So, Jamsie Poo, who's the not so lucky girl of the week?" Sirius Black asked, thumping his best friend, James Potter, on the back.

James was sitting in one of the red, squashy armchairs by the fire in the Gryffindor Common Room. He had not finished his assignments, and didn't plan to either. Sirius took a seat next to him, grinning widely.

James grinned, his hazel eyes sparkling. "Vanessa McKinnon," he answered.

James Potter and Sirius Black were two of the most eligible bachelors at Hogwarts School of Witchcraft and Wizardry. Sirius was tall, dark, and handsome. His black hair was rather long, but he looked 'so darn sexy', as most girls would agree. And never was a strand of hair out of place. Sirius was also known for his motor bike, which he would take 'special girls' for a ride on. A ride straight to the Astronomy Tower, where they would have a quick snogging session. James Potter was of average height, and had messy hair, that most girls found adorable. He was known for having a new girl on his arm each week. James' longest relationship lasted for six days, because they had two days off to visit Hogsmeade before the Christmas holidays. Both boys were mischievous Fifth Years at Hogwarts, and partially formed the elite pranking group known as the Marauders.

"Hufflepuff with nice legs, right? Good choice, chum," Sirius said. "But not much of a challenge…"

James frowned. "What's that supposed to mean?"

"Well, I would like to see you go after a girl who wasn't head over heels for you already," Sirius answered.

"There isn't one at Hogwarts," James said triumphantly, leaning back in his armchair.

James and Sirius jumped as they heard a girl scream, "POTTER!" They watched as Lily Evans appeared from behind the Portrait Hole. "You are twenty minutes late for the Prefect meeting. McGonagall is going to have your head on a silver platter this time!"

Lily Evans' green eyes flashed in anger as she stood with one hand on her hip. She stood straight as a board ('Damn good posture', Sirius had said. 'Probably a good snog') her chin up.

"Evans, can't you see I'm in a meeting right now?" James said coolly.

Lily frowned, as she smoothed her bun. "Well, it's your funeral." She gave the two boys one last glare before exiting the Common Room.

"What a bloody witch," James muttered, turning to find Sirius grinning. "What?" he asked nervously.

"James, my friend, are you up for a challenge?" Sirius asked.

James pondered this. And then his face fell. "Oh no. No no no! You are not even thinking that!"

"I, Sirius Black, challenge you, James Potter, to make that Green Eyed Monster fall for you."

James frowned deeper. Sirius knew that he could never back out of a bet. "How long do I have?"

Sirius looked up at the ceiling. "Well, since it's Lily Evans… I'll give you until the end of the school year."

"And if I win?" James inquired.

"I'll give you 200 galleons and drop out of the running for that contest the Ravenclaws and Hufflepuffs are running. 'The Sexiest Male at Hogwarts', I think. But if you lose, you owe me 100 galleons, you drop out of the contest, and you have to publicly admit your defeat."

James reached his hand out to meet Sirius'. "You have a deal."

Lily Evans smoothed her robes down as she stood up. The Prefect Meeting had just ended. They had sent her to get Potter because they had to vote on the some matters, but that prat wouldn't come, claiming he had more important things to do.

"Ella!" Lily called out, walking to meet her best friend. She didn't walk any faster. Lily just assumed that Ella would wait for her, which she did.

"Hullo. How's Potter?"

Lily stopped. "Why do you ask me that?"

"Well, you came back without him, and looking upset. And you just said that he couldn't make it." Ella gazed at Lily. Ella had shoulder-length brown hair, and bright blue eyes. She had once dated James, but just because she had nothing better to do. She had lasted four days.

Rolling her eyes, Lily answered, "he was in a 'meeting' with Sirius Black. Probably planning another hair-brained scheme." Lily took a moment to gaze at her watch. "We're thirty seconds late for dinner."

"Lily, you are too perfect, I swear. If I wasn't your friend, I would swear you were a monster!" Ella said jokingly. Lily softened up.

"I guess I can spare a minute or two. I'll just have to miss a little sleep. I have five more chapters to go in my book!"

"You and your books!" Ella scoffed.

Lily gazed dreamingly at the ceiling. "But it's getting to the good part. The fair maiden is trapped in the tower, while the prince is fighting off the goblin to rescue her!"

"There's more to life than reading and punctuality," Ella said, looking at Lily meaningfully.

"Yes. There's also grades and homework. Don't tell me you forgot to do the Transfiguration assignment." Lily gazed at Ella with her penetrating green eyes.

"I'm just going to claim that one of Kettleburn's beasts ate it… I have a fake paper that's all torn up and everything!"

"Ella, you have to be more responsible!"

"And you have to be more fun. Now, let's go to dinner," Ella said, putting her arm around Lily and dragging her to the Great Hall.
