The common room was quiet, save for the soft crackle of the fire and the occasional rustle of parchment. You sat on one of the couches, tapping your fingers on the edge of your mug absentmindedly, watching the flames dance. Mattheo sat beside you, lazily flipping through a book, though his attention seemed to drift more toward you than the pages.

You were both so caught up in the moment that neither of you noticed Theodore and Draco enter the room until they were standing directly in front of you.

“She’s mine,” Mattheo said without looking up from his book, his tone casual.

You froze, staring at Mattheo, unsure if you’d heard him correctly. “I’m yours?”

Mattheo finally glanced up, offering you a lazy smile. “Yeah, you heard me.”

Draco raised an eyebrow, surprised, and chuckled. “Wait, you two are dating?”

Mattheo raised his other eyebrow, clearly confused by the question. “No. What gave you that impression?”

Theodore gave a small shrug, his expression full of amusement. “I don’t know, man. Maybe the way you’re talking?”

Mattheo rolled his eyes and leaned back into the couch, clearly unbothered. “Okay, whatever...”

You couldn’t help but laugh under your breath at the absurdity of the situation, but as you looked at Mattheo, the lingering thought began to form.

You turned toward him. “Wait, hang on. Since when am I yours?”

Mattheo looked at you, a smirk tugging at the corner of his lips. “Since right now.”

Your eyes narrowed playfully. “You can’t just decide that I’m yours.”

Mattheo’s smile only grew. “Yeah, I can.”

You sighed, giving him an exaggerated eye roll. “No, you can’t call me yours unless we’re dating.”

Mattheo didn’t hesitate for a second, leaning forward with a gleam in his eyes. “Okay, then we’re dating.”

You stared at him for a moment, trying to process his sudden boldness. “Okay.”

Theodore’s grin turned into a mock pout as he looked between the two of you. “Well, that was easy,” he muttered.

Mattheo glanced at him, his smile still full of confidence. “Not as easy as you think.”
