Oh. My. God. This story is so beautiful. Several times I was on the verge of tears, but when I reached the end of the fic I was openly crying. I'm not a fan of Draco but the way you portrayed him and made him so human made me really like him. It was impossible not to.
I loved the boys (they are adorable!)- shy Beckham, sensitive and sympathetic Al and of course James, who turned out to be a very mature boy, the complete opposite of his namesake. I loved your lively and vivacious Lils. And of course Scorpius. My heart was aching for both of them - Draco and Scorpius, when Draco was leaving. The scene broke my heart.
And finally I loved the relationship, the love that was slowly blossoming between Harry and Severus. And all this thanks to Draco. I really like what you did with the prompt. I mean, the way you "used" Draco in this story is very original and much more interesting than what the promp suggests.
