You and Draco are enemies

Draco always provokes you whenever he can with unfunny nicknames, embarrassing you and scaring you

You were in divination class and since there were no empty seats, you sat next to him

You were both looking at the crystal ball, bored

The crystal ball starts showing an image and Draco looks at it intently, with interest

In the image, it shows you and Draco kissing

Draco looks at you, surprised

Draco: What was that?
