And I forgot to mention something...
Draco’s tongue eased past his lips with a certainty he only showed when they were alone...

...Draco’s eyes were hooded, lazy with heat. He met Harry’s gaze. “What did you have in mind?”

This little bit spoke volumes to me. This really shows how much Draco has allowed his walls to come down for Harry. Maybe as he gets more used to showing affection for Harry, he can learn to be more open about his love for Harry too. :) *sigh*
