This takes place during Half Blood Prince. Ginny is helping Harry hide his borrowed Potions textbook and unexpected things happen. This world is all Rowling's. I do not claim to own the characters or the basic story.
Ginny said "Here, close your eyes and I'll hide the book."
Harry closed his eyes and moments later a pair of lips descended onto his. He wrapped his arms around the person and ran his fingers through their hair, only to stop when it was much shorter than expected. He opened his eyes and found himself not kissing Ginny as he thought, but an entirely different person.
"Malfoy!" He exclaimed.
"Yes, Potter?" Draco said with his mouth curving into a gentle smirk.
"Just what do you think you are doing!" Harry asked. Just then Ginny came walking up and looked at them questioningly.
"Just looking for some items of mine that I seem to have lost." Draco said and then strode away.
Ginny shouted after him "Don't get lost in here! It could take someone days to find their way out!"
Draco shouted back "Oh, please Weaselette do you actually think a Malfoy could get lost in just one room?"
"Lets just get out of here," Harry said and made his way towards the door.
"Are you all right Harry?" Ginny asked as they walked together.
"I'm fine." He replied. Later that night, Harry checked the Marauder's Map to see if Malfoy had actually made his way out of the Room of Requirement but didn't see his name in either the dungeons or roaming about the castle as usual. The next morning the teachers looked a little worried and glanced at the Slytherin table more than usual. So, Harry did what any sensible wizard would do: He told Ron and Hermione that he wanted some time alone and then skived off of his History of Magic lesson by saying he had a headache. He then made his way to the kitchen and asked the house elves for a picnic made of his favorite foods, and as an afterthought asked for Malfoy's favorites too. He wandered throughout the halls eating Bernie Bott's Every Flavored Beans until he came to the blank corridor where the Room of Requirement would appear. He walked back and forth three times thinking to himself Ͼ I need the place where things are hidden, I need the place where things are hidden Ͽ and a door suddenly appeared. He went in, not finding the piles of junk he expected, but someplace comfortable, with a roaring fireplace and arm chairs all over the place.
"Ah, Potter I see that you have some sense after all," Draco said from his place by the fire. "Judging by the size of that basket, you brought food for me too, yes?"
"Yes," Harry replied and set the basket down. "I thought I would have to search for you-" He was interrupted by Malfoy.
"Are you really that dim? Do you actually think the Room would let someone get lost if they didn't want to or let them stay here if there was no one to bring them food? The castle is alive Potter, whether you realize it or not."
Harry looked a little flabbergasted at that statement and sat down quickly. "What do you mean the castle is alive?"
"Granger must be the brains of your bunch, other wise how would you be alive?" Draco exclaimed. "The castle is imbued with magic from the hundreds of years of teaching. She has developed a personality and has a benevolent attitude towards the students who deserve it. Us in Slytherin have seen her do many things over the years but only because we are observant enough to notice it. I did not mean to kiss you. I just meant to hurry by without you seeing me but a brick came loose and I tripped. You see, Hogwarts has a way of bringing together the couples she thinks will be the best match."
Harry sat there in complete silence for a few moments and tried to absorb the information he was just told.
§ Meanwhile, elsewhere in the castle§
Ron really wasn't worried that Harry wanted to be by himself. Nope, he wasn't going to worry at all. "Yeah, Hermione?"
"Yes, Ronald?" she replied.
"Don't you think we should go look for Harry?" he said.
"No, Ron I don't think we should go look for him." She replied angrily. "How would you feel if YOU wanted to be alone and we came looking for you?"
"Well when you put it thaaat way." he mumbled. "I thought so." was her only answer.
"Well do you at least want to go get some lunch?" he said not a moment later.
"Honestly Ron, is that all you think about?" Hermione exclaimed.
"Well. no..." he said then grabbed her hand and pulled her off the floor where she was sitting. Suddenly, one or both of them (it was hard to tell who) lost their balance and they toppled to the ground. Ron looked deep into Hermione's eyes and kissed her, shyly at first then more urgently. Then, Hermione's stomach began to growl and they began to laugh.
"Lets go get lunch shall we?" Hermione said as she helped Ron off the floor. Ron smiled and threw one of his arms around her and off they went.
