I like the story and for me it's the first one on asexuality. Interesting, and a lot to think about.
I didn't spot the ending because I guess I was thinking about another matter, not quite related to the story.
I was thinking, asexuals should be able to love, right? But then, it was about eliminating the sexual tension so I guess that doesn't matter.
And kinda sad to see a nice guy like Sam being single, no?
I like the writing obviously. Some word choices made me smile, for example "Matt let the MATTer stew". Well, I'm not sure if you had written that intentionally, but then, I do like writing that makes me smile. For me, that's something about the author I like.
