Chapter 1: Off-Limits

You have wanted Wes Calloway since you were nineteen years old, and the whole architecture of your life has been built to make sure nothing ever came of it.

He has been your brother's best friend since they were twelve - in and out of your kitchen, at every birthday, the steady one in the photographs, the one who taught you to drive a stick in an empty parking lot the summer you were seventeen and laughed when you stalled it and never once made you feel small. And somewhere in there he stopped being your brother's friend and became the standard against which you have, quietly and disastrously, measured every man since, and you have never told a living soul, because there is a rule, old and unspoken and iron: your brother's friends are off-limits, and you are your brother's sister, and that is the end of it.

Now your brother is getting married, and you have driven six hours home for the weekend of it, and you walk into the rehearsal at the old country club with your dress bag over your shoulder and Wes is the first person you see. He is at the bar end of the room in a half-undone tie, taller than your memory keeps insisting he is, and he turns and sees you and goes still in a way you feel across the whole room, and then he smiles, and it is the smile you have been comparing other men's smiles to for a decade.

"There she is," he says, like he always says, the same thing he has said since you were a kid, and crosses the room, and hugs you - the same hug, the brotherly one, the safe one - except that this time it lasts a half-second too long, and his hand spreads warm and certain against your back, and when he steps away neither of you quite manages to make your faces normal in time, and your brother, across the room, is not looking, and you are grateful, because something just happened in that hug that has never happened in ten years of them.

"You're the best man," you say, stupidly.

"You're the maid of honor," he says, and there is something rueful in it, because you both already know what the wedding party seating chart says, what the processional pairs say, what the whole choreography of the next forty-eight hours says: that they have put the two of you together for all of it. Off-limits, and arm in arm, all weekend.

Chapter 2: The Pairing

They walk you down the aisle together at the rehearsal, your hand in the crook of his arm, and it is supposed to be nothing, it is supposed to be logistics, and it is the longest forty feet of your life. His forearm is warm under your hand. He matches his stride to yours without being told. At the front the officiant runs the couple through their vows and you stand beside Wes in the position you'll hold tomorrow and you are aware of every inch of the air between your shoulder and his arm, and when you sneak a look up at him he is already looking down at you, and you both look away too late.

There is a decade in the not-saying. You can feel it now, where for years you told yourself it was only on your side - you can feel that it is not only on your side, that he has been keeping the same rule you have, that the reason it has never once been a thing is not that he never wanted it but that he is a good man and your brother is his best friend and some lines you do not cross. The knowing is worse than the wanting was. The wanting you could survive alone. The knowing has two people in it.

At the rehearsal dinner you are seated together, of course you are, and under the table your knees are an inch apart and the inch is a live wire all through the toasts. He pours your wine without asking, the way he has done since you were old enough to drink it at these family things, and his fingers brush yours on the stem and stay a beat, and he tells a story about your brother at twelve that has the whole table laughing and you are laughing too and under the table his knee finally, gently, comes to rest against yours, and he does not move it away, and neither do you, and you sit there laughing at the right moments with your whole body singing one quiet illegal note.

Later, on the dark veranda, you find yourselves alone for the first time, the party loud behind the glass. He stands close. He looks at you too long, the way he has been failing not to all night. "This is a problem," he says quietly, and does not pretend to mean anything but the obvious. "Isn't it."

"It's been a problem for ten years," you hear yourself say. "I just always thought it was mine."

Chapter 3: The Night Before

He does not touch you that night. He is a better man than that, or a more careful one, and there is a wedding in the morning and a best friend asleep down the hall, and so on the dark veranda he just holds your eyes and says, low, "Go to bed," the way you imagine he has told himself to walk away a hundred times over ten years, and you go, because one of you has to.

But you cannot sleep, and you know, the way you have known important things only a few times in your life, that he is not sleeping either, two doors down in the old club's guest wing. The wedding is at four. After the wedding you go back to your city and he goes back to his and the rule reseals itself and you spend the next ten years measuring men against him from a safe and ruined distance. This weekend is the whole of it. This is all there is ever going to be, and it is slipping by in the dark a wall away from you.

At one in the morning there is a knock. Soft. You open the door and Wes is standing in the hall in a t-shirt with his hair wrecked from not sleeping, and he does not come in, he stays on the far side of the threshold like the doorframe is the last of his self-control, and he says, quiet and wretched and certain all at once, "I've kept this rule for ten years. I kept it tonight on that veranda when you looked at me like that. I'll keep it forever if you tell me to, and I'll be at that wedding tomorrow and I'll be happy for them and I'll let you drive home Sunday and never say another word."

He stops. His hand is flat against the doorframe, holding the line.

"Or you can tell me to come in," he says. "But you have to be the one to say it. Because if I cross this on my own I'll never forgive myself, and if I cross it because you asked me to, I'll never regret it a day in my life."

The hall is dark and quiet. The wedding is fifteen hours away. Ten years are standing in your doorway with his hand on the frame, waiting for one word, and your heart is going so hard you can hear it -
