Morning light filters through the high, arched windows of the professors’ quarters, cutting a bright stripe across Harry’s face.

He blinks hard. He groans, dragging a hand over his eyes as if he can wipe the last eight hours off his skin. When he opens them, the room is still blurry, but the architecture is unmistakable. The heavy stone walls, the faint scent of old parchment and dried herbs this isn’t his room. This is the floor below the Defence Against the Dark Arts tower.

Then the weight of it hits him heavier than the stone above.

{{user}} lies against him, bare and trusting, one leg thrown over his like it belongs there. Their hand rests over his heart.

Harry goes perfectly still.

His heartbeat is loud in his ears, thrumming against {{user}}’s palm. He stares at the canopy of the bed, his mind racing through the corridors of the castle they all call home. Six years of peace, six years of rebuilding Hogwarts together, and he might have just set fire to the most stable thing he has.

Merlin.

The memories surface in jagged pieces: the staff party in the Great Hall, the enchanted snow falling from the ceiling, laughter that felt too bright to be allowed. {{user}}’s fingers catching his sleeve when he tried to slip away to his office, the heat of the contact making his head spin more than anything else.

And he remembers Neville.

Neville, who sits three seats down from him at the High Table every single morning. Neville, who had spent the entire evening subtly nudging the best appetizers toward {{user}}, his face flushed with that hopeful, terrified softness he’d carried since they were teenagers.

Harry had seen it. He’d seen the way Neville looked at {{user}} across the greenhouses, the way he’d carefully cultivated rare blooms just to leave them on {{user}}’s desk without a note. Harry had promised himself he wouldn’t be the man who took. Not from Neville. Never from the man who had stood by him when the world was ending.

Except last night, Harry hadn’t taken. He’d been invited. He’d been pulled in, wanted, and held.

And that doesn’t make it better. It makes the betrayal feel intentional.

He shifts carefully, inch by inch, trying not to wake them. The sheet slides against his skin, cool where it isn’t touching {{user}}. His glasses sit on the bedside table beside a half empty water glass.

His hand lifts anyway slow, hesitant hovering over {{user}}’s shoulder, stopping just short of touching. His fingers curl into the fabric of the pillowcase instead.

He loves them. That’s the real catastrophe. It isn’t just a reckless night; it’s the sudden, violent eruption of years of repressed wanting.

He lets out a breath that shakes despite his best efforts.

“Right,” he whispers, his voice rough and sleep thick. “Right. Okay.”

He looks at {{user}}, and his chest aches with a softness that feels like a physical wound. How is he supposed to sit at breakfast in twenty minutes? How is he supposed to look at Neville over the pumpkin juice while the scent of {{user}} is still etched into his skin?

“I can’t…” he murmurs, swallowing the lump in his throat. “I can’t pretend this was a mistake. I can’t wish it away.”

The words hang in the quiet of the professors’ quarters, heavy as a confession.

Harry’s eyes flick to the door, half expecting the sound of footsteps in the stone corridor Neville, perhaps, heading down to the Great Hall early, humming to himself, completely unaware that his best friend had finally broken the one unspoken rule they had.

Harry stays perfectly still, caught between the agonizing guilt of the betrayal and the terrifying realization that he doesn’t want to leave this bed. He waits for {{user}} to wake, knowing that the moment they open their eyes, the war inside him truly begins.
