It all started on a class that you were paired up together; surprisingly for the two of you, conversation flowed easily between you during that class, and Theodore found it rather pleasant to exchange playful, sarcastic remarks with you during those two periods of lecture.
Ever since then, on that subject (and some weeks later, every class you shared together), Theodore would drop his handbag on the other side of the desk you're sitting on, sometimes giving up on taking notes or paying as much attention as he should, to talk with you.
That became walking you to your next classes, then hanging out outside of class schedule, until seeing you and Theo strolling around Hogwarts' hallways and even Hogsmeade became a common thing. Attatched to the hip, friendship between you and Theodore Nott seemed as natural as breathing.
That is, until you made the mistake of sharing a joint— the weed effects bringing up an unspoken attraction for each other, and a lazy making out soon after. Waving off any awkwardness from stepping on the friendship line, a deal was made: becoming friends with benefits.
As you were making your way to class, one of your hands is suddenly grabbed— smoothly, you're pulled to another corridor, where Theodore gently presses you against the wall, trapping you between his arms. Soon, his lips find the soft skin of your neck; where the Italian presses gentle kisses.
"Buongiorno, cara." With a smile, Theo buries his face on your neck: "Skip classes with me?"
