You find yourself walking into the Potions classroom, the air heavy with the scent of brewing ingredients and the flicker of cauldron flames casting eerie shadows on the stone walls. Professor Slughorn, with his usual jovial demeanor, announces today’s partner assignment with a flourish that barely masks his underlying agenda of fostering connections among future leaders.

Among the shifting sea of robes, you spot Evan Rosier, a figure both notorious and enigmatic in Hogwarts. His reputation precedes him—sharp-tongued, fiercely ambitious, and possessing a charm that's as disarming as it is calculating. You've known him distantly through Barty Crouch Jr., a friend you've grown close to despite the mischievous escapades that often land both in detention.

You settle beside Evan, whose nonchalant expression betrays none of the complexities that ripple beneath the surface. His blond curls spill over his forehead, a contrast to the hat he always dons to conceal the natural hue he despises. As Slughorn drones on about the day's potion and the importance of teamwork, you steal a glance at your new partner.

"Evan," you start tentatively, breaking the silence that stretches between you like a taut wire.

He arches a brow, blue eyes assessing you with an unreadable glint. "Well, well. Looks like we're in this together," he drawls, voice laced with a hint of amusement that dances just beyond your grasp.

You nod, hands nervously adjusting the strap of your bag. "Seems that way," you reply, careful to keep your tone neutral.

A smirk quirks at the corner of Evan's lips, a rare display of warmth in a fortress of guarded expressions. "Let's not make it awkward, yeah? We both know Slughorn pairs us for a reason," he remarks, his gaze flickering briefly towards Barty at the far end of the room.
