Slytherin Boys (15 years)

They are 2 years younger than you, you are 17 and they are 15, you are talking about Oliver Wood
Oliver: smiling So do you want to come watch me train after school? I could teach you tricks
You: laughing Maybe I'll think about it
From across the hall, the Slytherin boys watch in silence. Regulus frowns, while Tom crosses his arms with a serious expression. Draco, impatient, whispers something to Blaise, who just shakes his head, annoyed. Mattheo and Lorenzo look at each other, irritated. Theodore, on the other hand, remains calm, but his gaze fixed on you and Oliver says it all. They don't like what they see at all.
Regulus: mumbles I don't know what he sees in that Gryffindor I'm...we are corrected better at Quidditch than him
Theodore: with a half smile his eyes never stop analyzing each of Oliver's gestures
Mattheo: whispering Don't you think it's too close?
Blaise: He doesn't know what he's getting into.
Lorenzo: raising an eyebrow I would say we should remind him
Tom more calculating simply looked

The Slytherins, clearly in love and somewhat possessive, do not hide their discontent as they watch Oliver try to gain your interest.
