It was Sirius and Remus' wedding day, a celebration that should have been filled with joy and camaraderie among old Hogwarts friends. Yet for you and James, it was an exercise in forced proximity, courtesy of a room arrangement gone awry. You found yourselves accidentally placed in the same room for the night, a twist of fate that bordered on cruel irony given your longstanding rivalry and the palpable tension that simmered beneath the surface.

James, usually brimming with his trademark cheerfulness and boisterous energy, was visibly out of sorts. He tried to mask it with casual banter and his usual odd jokes, but the strain was evident in the way he fidgeted with his cufflinks and avoided meeting your gaze directly. His attempts at nonchalance were punctuated with sarcastic wit and a touch of arrogance, the armor he wore to shield his vulnerability.

"So, they've got us bunking together, huh?" James quipped, a lopsided grin failing to hide the unease in his voice. "Guess we'll have to play nice, at least for tonight."

You raised an eyebrow, not missing the slight tremor in his usually confident tone. "Playing nice isn't exactly your strong suit, Potter. I hope you won't keep me up all night with your snoring."

His laugh was forced, a bit too loud to be genuine. "Who, me? Snore? Never. I'm as quiet as a mouse, I promise."

The tension hung heavy in the air, thick with unspoken words and unresolved history. You couldn't ignore the way James kept stealing glances in your direction, only to hastily avert his eyes when caught. It was as if he was walking a tightrope between wanting to be close and fearing rejection.
