Trix. How long has it been since we've last been in contact? Too long, I'd say. I've been debating reading this intriguing-looking piece for a long time, and now that you have updated, I really couldn't resist.
And I'm so glad I finally have checked this out. Really. Everything was delightful, absolute wonderful. First, I have to gawk over Ginny' conversation with Tom. I don't think anyone else has specifically pointed this out, but it was a really good, seemingly slightly detached opening. It was personal enough to delve into the fabric of the world as it has become, but impartial enough for the audience to look on curiously, waiting to be beckoned deeper into the enchanting narrative. The comment about snow was, I think, like the What color is ice line in Flawed. You use an element of life, one used often in metaphor, and you still manage to twist it into something new, and translate it into something else, something infinitely more profound. I loved this part, and as I said, was a great opening.
Going into the Draco interaction - as others have said, it is very difficult to keep Draco in character when dealing with a romance between him and someone like Hermione or Luna or of course Ginny. However, I think it is much, much harder to keep him believable in a friendship, and especially so in one that you have masterfully illustrated, just in this chapter. From his reluctance to answer the door, to the shag/shave comment (which admittedly is another favorite line in this chapter) to the niceties they exchange after this dialogue, you've captured what a relationship that Ginny and Draco have developed ought to be, considering the context, as well. Absolutely astounding.
All that said, my absolute favorite part was the last two paragraphs. Phrases like "... his eyes a pool of boredom" add to the descriptive element you have done so well establishing in your writing. And his action in that last section was a very controlled burst of anger, something seemingly random but I am guessing hints at difficulties to come. Perfectly Draco Malfoy, if anything was. And that last line was perfect. Perfect. Concise, and gets the point across without fluff, it is very rough, and - I can't say this enough - so like the Draco you have so skillfully portrayed.
I can't praise you enough on this thoroughly wonderful first chapter, and I am impossibly happy at having another chapter to see more of where this story is going - and oh, the places it'll go!
