Thank you for reading through the fic, infidelity notwithstanding! I'm flattered that this infidelity fic worked for you...although I have to admit, I don't run into infidelity fics very often so if you have any links to ones you've bumped into, I'd be interested in seeing them myself as I have no qualms about reading them! :)
I'm especially happy that you found the non-angst-ridden tone appealing, because I was hoping for an infidelity fic (which tend to be inherently angsty) that was just...quieter, you know? Like infidelity IS a terrible, terrible thing, but how terrible is it, really, if no one knows and there are no consequences re health and the like? Is it just intrinsically bad, for reasons of morality? Severus isn't being unfaithful in terms of his feelings--his heart is Harry's, and I hope that came across okay in the fic. Anyway, I'm getting boring and serious but these were things I thought about while writing...not that I necessarily reached any conclusions!
