You were promised to the crown prince before you understood what it meant to belong to someone who would never fully belong to you. The court called it fortune, something fixed and enviable, and you learned not to question it. Phillip grew into his role exactly as expected, composed, distant, always pulled toward duty first. And beside him, always a step behind, was his younger brother.

William was never meant to matter in the same way. The spare, shaped more by steel than ceremony, more familiar with training grounds than courtly halls. Where Phillip was measured and untouchable, William was grounded, present, his attention sharp in ways that felt almost instinctive. And somehow, without ever being asked to, he was always there when it came to you.

Not in ways that could be questioned. Just consistently.

Where Phillip’s absence became something you learned to expect, William filled the space without claiming it. He walked beside you when no one else did, stood where the crown prince should have been with an ease that made it seem natural. To the court, it was courtesy. To you, it became something harder to ignore, because it never asked to be named.

He noticed things Phillip never did. The way you stopped waiting in certain places, the quiet shifts in your habits, the way you spoke less when you no longer expected to be heard. William never pointed it out. He simply adjusted, meeting you where you already were, as though he had been paying attention long enough to know you would end up there.

That was what made it dangerous. He never asked for anything, but he didn’t step away either.

There were moments when his restraint showed its strain. A glance that lingered too long, his attention heavier than it should have been. The way he stood just slightly closer than necessary, close enough that it felt intentional. Once, his hand brushed yours and didn’t pull away immediately, his fingers tightening just faintly before he forced himself back. It was never enough to cross the line. Just enough to prove he knew where it was.

And still, he stayed.

Without meaning to, you began to look for him first. In crowded rooms, in quiet corridors, in moments where your attention should have belonged elsewhere. You spoke to him without thinking, trusted him with things you had never even tried to give Phillip. William never corrected it, never reminded you of what this was supposed to be.

Because some part of him didn’t want to.

By the time the gathering arrives, it no longer feels accidental.

The room is filled with expectation, every movement watched, every absence quietly noted. You stand where you are meant to, composed, the future queen in everything but certainty. Phillip is absent. Again. No one remarks on it.

You don’t look for him.

Your gaze shifts instead, instinctive, and finds William across the room. He is already watching you, something unreadable held too tightly beneath the surface. When he moves, it’s without hesitation, crossing the distance with the quiet certainty of someone who has already decided where he belongs.

He takes his place beside you, close enough to matter, careful enough not to be questioned. His presence settles there, steady, unyielding, as though he has done this too many times to pretend it is anything else.

For a moment, neither of you speaks. The noise of the room fades at the edges, leaving something quieter, heavier.

His hand shifts slightly at his side, like he’s about to reach for you, before stopping himself. The restraint is visible now, not hidden, something deliberate, something chosen.

“If he won’t stand here,” William says, “then I will.”

And that is where it becomes something dangerous.

Because he means it.
