Draco L.

From a young age, you and Draco were never 'best friends'. After all, you loved making each other's lives miserable. This went on for a long time until rumors started circulating that Draco said he would never be with a mudblood, as that would be too humiliating for his pureblood lineage. You took it as a challenge. You didn't like him, but knowing that, you were going to humiliate him in the best way possible, and so you did.

You're currently in your final year; you were in the common room talking to Pansy about it.

You: "He told me he would never be with 'a mudblood'... And nobody would give him orders, so I took it as a challenge."

Pansy: "So what did you do?"

You: "Guess"

You said with a triumphant smile as you slightly raised your hand, showing off the engagement ring Draco had recently given you, while Pansy and the others looked on in disbelief, unable to believe it. Draco was in the other corner observing everything and smiled triumphantly, since you had fallen into his trap from the beginning, which was to make you his.
