This is based more on the movie, as I could never do the book justice.
Tear it apart. Kill it.
Polka dotted and make-up splattered, Lavander Brown planted her bulbous lips on Ron Weasley's. All the Gryffindors roared like their animal emblem, Hermione even noticed a slight grin on Harry's shocked, yet amused, face. She did not share such enthusiasm, instead bile rose to her throat and her heart felt like it had been torn out of place.
Hermione Granger sprinted out of the Gryffindor common room and went downstairs, wanting to put as much space between herself and the makeout scene taking place. Ever since Ron had opened his arms for her at Buckbeak's execution, she thought he would always be there, arms wide, ready to embrace her anytime. Even though she'd never admitted it, even to herself, she knew that she liked him; like likeed him. Now that dementor of a girl, Lavander Brown (what a stupid name), had come sucking out any happy feelings she had towards him. Hermione gagged, seeing the image of Lavander's mouth against Ron's in her mind.
Hermione stopped running and grabbed her stomach as bile flew from her mouth. Mouths, the thought just made her feel worse. She collapsed onto the seventh floor platform, curling up in a ball. She cried away any hope of a life with Ronald Weasley.
Hermione heard a creak behind her and jumped in fright. "Who's there?" she asked, a shiver running down her spine. No one answered, but the creaking continued. She collected all her Gryffindor courage (for at that moment she would have rather stayed on ground until she died of dehydration) and stood up, turning around to face the corridor. On the far end oc the corridor wall, Hermione saw the Room of Requirement doors slowly closing. Hermione found her strength and ran until she pushed open the doors and fell inside, for at that moment she required something more than anything; something to take away the pain she was feeling.
She didn't recognise the room in this form. It looked like an old junk shop, with a neverending supply of disgarded objects, stacked right to the ceiling. There were half torn sofas, piles of books (which she would have fancied exploring if she hadn't been in a state of despair) and even a broken record player. Hermione walked deeper into the room, looking at the strange objects through tear-flooded eyes.
Suddenly there was a crash to her left, Hermione gasped and swung around. Facing her was Draco Malfoy. He looked scared out of his wits, a state she had never seen him in before. He almost seemed human.
"Grang... Granger." He stuttered and fumbled with the Hawthorne wand in his shirt pocket. Hermione thought he must have been in shock at seeing her there. She reasoned that this part of the Room of Requirement was a place where people hid things, a place where they hid themselves.
She took one step towards him. "I guess we all have our secrets."
