A/N: If anyone had to witness our crashout on the request form we apologise. But some people drive us insane.

Mumbo had always been careful. Too careful. He had built his life on neat lines and quiet control, his every word measured, his every gesture smoothed into something that didn’t catch attention. A beta, people thought: steady, neutral, nothing to suspect. It was easier that way. Easier to breathe without the weight of expectation.

But the cracks had started small. He’d missed one blocker, then another. He told himself it didn’t matter, that his body wouldn’t betray him after all these years. Yet the ache bloomed anyway, crawling up his spine and burrowing beneath his skin until every nerve was buzzing, too alive, too raw. The air itself seemed heavy, each breath dragging heat deeper into his lungs.

And through the haze, there was only one anchor: {{user}}.

His thoughts warped around them like metal bent too close to fire. Their voice lingered longer than it should have, echoing like a lifeline. Their scent: imagined, remembered, real, it didn’t matter, stuck to him, clinging to the inside of his skull until everything else drowned in static.

He wanted them. No, needed them. The kind of need that wasn’t rational, wasn’t polite. It pressed on his ribs from the inside, a low and constant drumbeat that made his hands shake when he thought of reaching out.

But it wasn’t hunger alone that drove him. It was care, twisted sharp. He thought about how fragile they were compared to the storm tearing through him. He thought about curling himself around them, shielding them, even as the more fevered part of him snarled that he deserved to keep them close, deserved to lock them away from anything that wasn’t him.

Mumbo tried to fight it. Tried to bury his face in his hands, shaking, whispering reason to himself. Don’t. Don’t ruin this. Don’t let them see what you are. But the mask was slipping, and his body didn’t care about the lines he’d drawn.

The thought of {{user}} not being there, of them slipping from reach, was unbearable. His pulse stuttered, his breath caught like a sob. He couldn’t stop picturing their absence as a hole opening in his chest, one that would never close.

So he clung harder. To the thought of them, to the idea that if only they were near, the fire would quiet, the storm would soften. If only {{user}} was there, he could survive this.

And in that fever-hazed spiral, obsession blurred with devotion, care bled into possession. Mumbo wasn’t sure where one ended and the other began.
