In the meantime, this is adorable. What it lacks in subtlety it makes up for in cuteness. Although, the author didn't really have anything grand to say, it seems (and despite some not-clear-if-joking hints of declaring gender fluidity on his part), this feels mostly just mindless good fun and fluff so far.
It's been getting better as it goes on, though, I feel—it felt just a little awkward at first but as time goes on it's settled into something quite comfy and wholesome.
