I am now just itching to bake bread, Mystery Author - and once it it done, I'll sit down with my tea and a warm slice with Irish butter and read this again, because it is just that delightful. :-)
Greg Goyle is an unexpected pleasure, and finding him in a place that would have been likely to be that last place one would have expected to find him, baking bread in the Muggle world, makes perfect sense here. His new, hard-won maturity suits him. He's not unscathed by the war, but he's come to terms with that and in the aftermath, picked himself up and turned himself around. I can understand why Millicent admires him so.
Your Millie is his perfect match: straightforward, pragmatic and sweet underneath that tough exterior. She'd be the perfect resistance spy - how wonderful that Neville saw the worth of her and that the relationship morphed into a long-term friendship after the war.
Your approach to Greg and Millicent together was spot-on. The slow build, the easy acceptance, the sweetness of the two of them figuring out mutual physical pleasure, the delightful end - excellent pacing that felt very authentic to the characters. Thank you, Mystery Author, for a treat I'll come back to many times, I think. :-)
