A/N - this is 100% not self projecting about wanting Sebastian to be mean to me

Sebastian had told you to meet him in Professor Hecat's classroom well after her classroom hours were over. You were only on your way there because you assumed he wanted to settle things between you two with a duel. You were both constantly at each other's throat and had way too much free time in your 7th year to be constantly trying to best each other at everything.

You hated how well he did in his classes despite being there about half of the time and turning in homework even less than that. You thought he was fairly self-absorbed and dragged Ominis around on a leash rather than treating him much like a friend. Your relationship with Sebastian had been like this since the day you got sorted in Slytherin.

He was arrogant and it pissed you off just thinking about him on your way to the classroom. It made you even more mad when he had come back this year no longer just some annoying kid, but very much looking like a cocky man.

You didn't know why it stunned you so much to see how he filled out with broad shoulders and a much thicker jawline. You chalked it up to bothering you because you were worried his dueling would somehow be different, as if his physicality really had any affect.

In fact, you also didn't know why you bothered with his stupid request that you were headed on now. For all you know he was trying to set you up to look like you were in the wrong place at the wrong time. You justified your journey by thinking at least you could put him in his place for thinking he had any right to send you owls requesting your presence somewhere.

You pushed open the door and made your way into the room, scanning for Sebastian so you could get this over with. You saw him standing at the balcony to the professor's office as if he owned the place. You crossed your arms at how smug and comfortable he looked, resting his arms on the banister.

"Ah — Y/N — I knew you would come."

You stalked towards him with your wand in hand, your face heating up in anger.

"What are you talking about? I came to tell you it is not ever your place to send for me. I don't know what potion you drank that made you think we're cordial, but I'm only here to remind you that I can't stand you. And the next time you send me a letter, I will jinx it and send it back."

You stood at the foot of the steps looking up at him, still very unsure of what this situation was. He simply looked down at you in amusement as if your words weren't laced with venom. You noticed he had exchanged his uniform for the day with a knitted sweater and some pleated trousers.

"And your dressed like, like this is some house call? What do you want Sallow?"

You crossed your arms over your chest and glared at him, more fed up by the second.

He stood up straight and gestured at you with his hand, "Come up here and I'll tell you."

"What game are you playing? I do not have time for this," you stomped up the stairs feeling almost tempted to use an unforgiveable on him, "What the hell am I —"
