Her robes skimmed the dark potions classroom, while the girl in them fretfully cleaned the floor, on which her potion spilled, ruining her grade, and causing a very stupid detention. She scrubbed with the already dirty brush on the floor. The potion just wouldn't come off. She rubbed the sweat on her forehead, and scrubbed harder. Who knew draught of living death would stain the concrete floor?
She scrubbed harder, thinking of how she stupidly spilled the potion, looking at her boyfriend. Oh, how she hated how he came back to Hogwarts, after the final battle. She hated that he was now in her year. She hated how she could never concentrate with him around. She hated how he would smile, and wink at her, and hold her hand in the hallway. She hated how she never studied with him, because he was too much of a nuisance.
She heard footsteps enter the empty potions room. Predicting it Slughorn, she continued scrubbing the floor, even harder now. The footsteps were slow and intimidating. She slowly peered up; fearing who it was would make her stop cleaning.
He smiled at her, with that award-winning smile. She couldn't stop herself from smiling back at him. He leaned down, and kissed her cheek sweetly. She blushed. He conjured a brush in the air, and started scrubbing with her.
She looked at him with confusion. Wordlessly, he apologized, with his eyes. She wordless forgave him, and started scrubbing again.
She knew she would never hate him again.
