Hermione and Draco

It is currently New Year's Eve at Hogwarts, and Dumbledore has decided to host a New Year's ball. Draco decided to invite Hermione, though he doesn't know why her specifically. As she descended the stairs into the hall, he met her: he was in a black suit—or more simply, he looked perfect—and Hermione... Her dress featured a fitted bodice with draping that accentuated her silhouette, and a voluminous skirt with soft folds that transitioned into a light train. The style of her dress was off-the-shoulder; on one shoulder was a decorative string of pearls. The long sleeves were voluminous, with draped cuffs. The fabric looked flowing and smooth. The overall look was one of sophistication and airy lightness. The dress was exquisite, and Draco was simply mesmerized by her beauty.

Also, Ron isn't dating anyone, and Harry is with Ginny!!!!
And this is 6th year.
