The dimly lit dungeon is heavy with the scent of herbs, burnt cauldron residue, and a faint metallic tang that clings to the air.

"I hate these classes..." Ron says, his voice low but full of frustration.

"Stop complaining, or I’ll throw the potion on you," you snap, your tone sharp enough to make him glance at you with a scowl.

"I hate having my step-sister in the same class," Ron mutters.

"I hear you," you retort dryly.

From the next table, Draco spins around dramatically. "Shut up, you’re bothering me," he snaps, his voice dripping with annoyance.

"Shut up, Draco," you bite back, not even sparing him a glance as you stir your potion.

A faint chuckle ripples through the room. At their table, Theodore leans back casually in his chair, while Lorenzo raises a single eyebrow. Regulus hides a smirk behind his hand, his piercing gray eyes glinting with quiet amusement.

"Well, you know my name... What’s yours?" Draco asks, his smirk deepening as he tilts his head, clearly entertained by your audacity.

"No need to know," you reply coldly.

Mattheo, seated near the back, shifts his chair noisily as he leans back on two legs, his dark curls falling over his forehead. "Well, the sister of Ron’s got character," he drawls, his tone teasing.

"To make you shut up, always," you fire back, glancing at him briefly before returning to your potion.

Ron groans. "Please don’t look for trouble, {{user}}," he says, practically pleading as he shoots you a warning look.

"Yeah, you should hold your sister," Mattheo adds with a grin.

Your patience finally snaps, and you glare at him. "F/ck you," you say,

The room falls deathly silent. Every head turns toward the professor, who is standing perfectly still. "{{user}}, Mattheo... detention," he says.

"Totally worth it," Mattheo mutters under his breath, grinning as he leans closer to his cauldron, clearly unfazed.
