Oh, man, this was brilliant! They were so genuine and unrushed and so... teenage, LOL! I loved Harry's perspective like I never knew I would and I really appreciated how very much in character they were. I loved how Ron tried to make the right choice by picking the robes his mother had sent - but the twins would not let him have any of that rubbish and he just knocked Harry off his feet.
I giggled like a loony countless times (Malfoy getting a measure of instant-Weasley-payback, LOL, and Harry's vision of having to go to dance with Trelawney were super precious) and it was lovely to see you incorporate the story into the canon the way you did.
The last chapter was super hot and I thought it was great how you didn't write them rushing into things head-on, but it was still sexy and hot and kind of glorious.
Wonderful work! :)
