Things to Remember
James is quite smitten with Lily, which she can't understand and then tries to ignore. Later the fact that he's always trying to ask her out becomes quite annoying, since she can't see why a handsome boy as himself would ask her out and she makes herself believe that it's only because he wishes to humiliate her in front of the whole school. And on that basis she begins to hate him. James keeps on trying, however, but after numerous rejections she mysteriously accepts around Easter in their sixth year. Something happens that make James give up on her. But then she suddenly realises she like James, but she can't just start saying the opposite after all those years. She tries in several small ways to make him try again, but it isn't until she, as Head Girl, rises to sing again at the beginning of their seventh year at Hogwarts, which is also the schools one thousandth year, that he realises that he can't give up. And finally, at a ball around Christmas they realise that they're meant for each other and start the relationship the whole school saw coming since they first met.
Remember that Lily has skipped her second year and is one year younger than the rest.
And about the Animagi transformation: Remus and Peter are best friends, and together they have gathered all the information they would ever need in mastering the animagi transformation. But they realise that they won't be able to go trough with it without any more help. And that help appears in the forms of James and Sirius, which immediately take a liking towards the two Gryffindors. Not to long after the Marauders are a fact.
School Issue: James begin his magical education at Hogwarts but transfer to a foreign school after his first year, that's why he don't know Lily. Sirius, on the other hand, was sent to the foreign school immediately.
Proposal"I remember the first time I saw you. Standing on that stage singing out your song ever so boldly, every note ringing out as pure and clear as the most innocent of the angels, as powerful as the mightiest lions roar. And I knew instantly that there could be no one else but you. But still, fighting the voice in my head with every step, I walked away from you, thinking that you'd never have me, and if there ever would be a time when such a thing were possible, you'd be taken, and you'd be perfectly happy. I mean, how could a so heavenly and divine creature as yourself be left alone for even a single moment. But Destiny was kind to me, and I found you on that stage again, singing out your song as if your very life depended on it, putting your heart and your soul and your mind into it, like you always do. And as your voice filled my ears, the sight of you left me breathless, in desperate need of the touch of your hand, the smell of your hair and the taste of your lips. You let me into your life again, and my love for you has only grown since that day, and it will continue to grow every day, even beyond the days of our life. But my life, I knew, would not be complete without you by my side, in every eye and in every mind, be there no doubt about that. But would you grant me the gift of you? A gift so heavenly and out of grasp that a man should fear to think of it, fear that one word that can wreck a human heart within a single beat. Still I will dare to think of it, and I will dare to ask it. Knowing that in my heart I love you more than life itself. Will you marry me?"
