As you know from the email I wrote when I was halfway through my sneaky-because-still-not-finished-writing-mine reading, I love your story. And you know what? I was honestly surprised to see the prompt for "infidelity" there when I finished reading because...okay, it's not as if I didn't notice, but it seemed so right for this story that I didn't see it as "a kink I don't like" but as "part of Harry and Snape's real life." Well done! I'm adding this to my recs page when I next update.
