I really liked that this was a slow-burn piece, even if the short story happened within several hours of Henry and Marc being trapped inside the car during snow storm. I enjoyed the tension in that small space. The ending was a tentative HFN but it felt right because these two definitely still need time to work things out.
BUT, it will probably be a better story for me if I can get Marc's own POV. Clearly Henry didn't understand Marc that well. Considering the story was written solely from Henry's perspective, to me, Marc was still an enigma. Especially in regards to his confusion about his sexuality and his feeling towards Henry.
