I have to confess this was difficult to read, though in the best way possible.
My heart was aching for the Harry and Severus of the present while reveling in the glimpses of the past. The New Years' scene had me eagerly anticipating the next bit, but I was wanting to bolt out of my room along with Harry when he visited Severus' office.
I love stories that have me feeling as though I'm living the story right along with the characters, even if it's only for a bit of time, and this story certainly captured that sensation for me, so thank you.
