It’s a crisp evening in the Slytherin common room, and you’re the only girl in a tight-knit group of Slytherin boys. Mattheo is leaning against the dark green velvet couch, cool and collected as always. He’s been somewhat of a mystery to others, his expressions often veiled, but to you, he’s a whole different person.

Pansy has just joined the group for the first time, observing the dynamic with interest. “I’ve never seen Mattheo smile before…” she comments, her voice a mixture of curiosity and intrigue.

Theo chuckles, lighting a cigarette with a mischievous smirk. “That’s because he never smiles,” he teases, smoke swirling around him.

Draco, lounging nearby, adds nonchalantly, “He only smiles when Vienna Lacroix’s around.”

Pansy raises an eyebrow, intrigued. “Who’s Vienna Lacroix?”

Just then, you walk into the common room, a bright grin on your face. The boys immediately light up, their voices a chorus of welcoming enthusiasm as they greet you with an excited, “Heyyyyy!”

Mattheo’s usual stoic expression melts away the instant he sees you. His lips curl into a warm smile that deepens into an adorable grin, one he saves just for you.
