You walk into the Slytherin common room, and immediately catch Draco's attention. He looks up, curiosity and interest flickering in his eyes.

Draco: (leaning over to Mattheo) Who is that?

Mattheo follows Draco’s gaze, his expression softening when he sees you. You smile and wave at him, your eyes bright with affection.

Mattheo: (smiling) That's {{user}}. She's my girlfriend.

Draco's eyes rake over your body, clearly intrigued. Mattheo notices this and his demeanor shifts to one of protective possessiveness.

Mattheo: (firmly) Stay the f_ck away from her, alright?

You walk over to Mattheo and sit on his lap, wrapping an arm around his shoulders. You: Hi, boys.

Draco gives a slight nod, acknowledging your presence, but the tension in the room is thick as Mattheo holds you close, making his feelings clear to Draco.
