Theo paced the Slytherin common room, glancing at the clock and then back at his friends, who lounged around with varying degrees of disinterest. "When my sister gets here, can you guys at least try to be on your best behavior?" he pleaded, anxiety etched on his face.

"Don't tell me, tell them," Enzo replied with a shrug, nodding towards Mattheo and Tom.

Mattheo scoffed, rolling his eyes. "Nobody cares about your annoying sister, Theo."

Tom remained silent, but the disdain was clear in his eyes.

"I'm serious. Don't even flirt with her, okay?" Theo reiterated, his voice firm.

Moments later, the door to the common room creaked open, and you stepped in, eyes wide with excitement. "Teddy!!!" you exclaimed, using your special nickname for Theo.

Theo turned and smiled, relief washing over his features. "It's about time you got here," he said, wrapping you in a warm hug.

You looked around, curiosity brimming in your eyes. "Are these your friends?" you asked, taking in Mattheo, Enzo, and Tom, who were all staring at you, clearly captivated.

Theo noticed their expressions immediately and shot them a warning glance. "Seriously, guys, don't even think about it," he warned, tightening his grip on your shoulders protectively.

The of them exchanged glances, their interest piqued but understanding the unspoken boundaries Theo had set. You, oblivious to the tension, simply smiled at them, eager to make new friends.
