We've known each other for such a long time, and I think you know exactly who I am already, so I'm not going to take the time to tell you. After all, my name will appear at the bottom of this letter anyway. (Formalities always have a way of getting lost when I'm talking to you.)
I just wanted to let you know a few things. First of all, all my fellow Slytherins keep shooting me these dirty looks, like they know this letter's for you. How would they know that, though? I'm getting off track again, and I know you'd be looking at me in that impatient way you have.
I know by the time you read this, you might be happily married to a James Harold Potter that we both know and one of us loves. (The other thinks he's a slimy git who doesn't deserve you.) But… I just wanted to say this one thing to you.
I love you. I love the way you smile when you think about something that you love, I love the way your hair falls in layers around your face, I love the way you scrunch up your nose when you're thinking hard. I love the way you hold your head when my housemates are tormenting you, but most of all, I love the way that your eyes shine when you laugh.
So this morning, the last day of classes before we graduate from Hogwarts, I sat down in the Slytherin common room, and, housemates glaring at me, wrote you this letter.
And I know that by the time you finish reading this letter, James will have come in and read most of it over your shoulder, so, hello, Potter. So know that while I was tucking this letter into your potions book, I was thinking about how this is all so wrong. I know that you and James will be happy together, maybe you'll bear his children, but I just wanted you to realize what you've done to my heart.
If you look into your school bag, you'll also find two small vials. One, the gold one, is Felix Felicis, as you no doubt know. I made it during the school year, as I had almost none of the ingredients at my home over the summer.
The other bottle is Veritaserum, and I can only hope you use it wisely.
I know the next time we see each other, we'll have to draw wands against each other, so all that is left to say is simple.
Good Luck.

James Potter-
Treat her well. I know you love her as much as I do, but if I hear you've hurt her, you'll have me to deal with.

Lily couldn't suppress the dry sob that seemed to burst from her throat. She sank onto the sofa, her letter clutched in her hand. He had cared so much about her, at least as much as James. Another sob racked her body as she realized that she may have gotten stuck on the side of the triangle she didn't want to be on.
The note addressed to James Potter sat unnoticed under the sofa for three long months, until the day came when James dropped his wand in the sitting room. He unfolded the note slowly, not sure what to expect, but as he read it, his eyebrows shot up onto his forehead. He had cared. He had cared a lot, and was willing to find James if he ever hurt her. It was a wake up call for the young man, who until that moment, had not realized how lucky he was.
