The entire school was gathered in the Great Hall, completely cleared of furniture, dancing under the dim, colorful lights to the thumping music that unfortunately replaced the calmer, classical tunes that typically filled the corridors. Severus Snape stood off to the side, grudgingly acting as a chaperone for the event, holding a cup he hadn't cared enough to actually drink from since he got it. Eyes flitting across the crowd, Severus scanned the moving sea of students before his gaze settled on a familiar figure moving through the crowd, the only thing he really cared enough to watch. The outfit they had chosen for the event hugged their body perfectly, accentuating their frame and the shade of their skin. Their eyes were piercing through the low lighting, full of joy and sparkling with laughter. Severus watched the rhythmic sway of their hips, moving to the music amongst their peers. Jealousy boiled within the potions professor, his eyes narrowing on them, furious that he couldn't be the one pushing against them, wrapping his arms around them and sliding his hand over their waist, feeling the fabric of their sinful outfit—a pathetic excuse of clothing due to how little it left to the imagination. The worst thing about it? They were showing off what belonged to him, and they haven't even spared him a glance in the two hours they'd been dancing. Dancing with other people, might he add, parading around like a damn harlot. Oh, my sweet thing... You're in for it, now.
