After all this time

For five years Grace and Andrew keep an arrangement that neither of them names in front of anyone else. He is in it for the sex, and she has spent the whole of it waiting for him to want more than that and say so out loud. Then she is pregnant, and the arrangement will not hold. Andrew marries her. Something that began as an accident becomes a tie neither of them can get out of, and once they are actually living beside each other, their university years start coming back up. The two of them were tangled together well before the five years began, and Grace has not known the whole of it.
