Summary: Draco and Hermione are Potions Partners for a week. They're the smartest seventh years students, so it shouldn't go wrong should it? Watch how a few potions change their relationship in only one week.

A Potion A Day Keep's Who Away ?

The Cadena Potion

Our story begins a sunny monday morning, however rare they may be, on the grounds of the wizarding school Hogwarts. Birds, though not any kind we muggles know of, are singing happily and the sun is reflected in the big lake where the Giant Squid occasionally breaks through the surface of the water to playfully catch some insects.Smoke is rising from the chimney of Hagrids hut and Fang growls lazy at a squirl, of course from a safe distance.

But despite this decieving peacefull scenery a 'war' of a sort was going on inside the stonewalls. Oh yes, it is of course the never ending war between two of four houses Gryffindor and Slytherin. 'Fighting' on the green and silver Slytherin side we have Hogwarts badboy Draco Malfoy and on the opposite red and gold Gryffindor side we have Hogwarts know it all Hermione Granger.

The two of them would try to stay clear of each other through out the school years, but of course they occasionally met and insults and hexes were generously thrown at the other. Draco hates Hermione for being a, in his words, mudblood know it all and Hermione hates Draco for being an arrogant git.

At the moment Draco is busy trying to escape the imprisoning arms of Pansy Parkinson while Hermione is trying to comfort poor Neville Longbottom who fainted as soon as he saw that they did in fact have a Potion class every day of the week this year.

The two rivals has no idea what this will mean for both of them, but oh it will most definetely be affecting them. In the Great Hall at breakfast they don't exchange a single word, they simply glare at each other once when their eyes caught each other.

"All I'm shaying ish that" Ron Weasley's voice sounds next to Hermione, his words not pronounced correctly because of the amount of food he's trying to chew at the same time "Potion's everysay is blooshy awfull." small bits of food fly out and Hermione can't stop herself from wrinkling her nose disgusted "No Ronald, it's 'Bloody awfull' honestly aren't you too old to be talking with food in your mouth?"

The only answer she get's is a foolish grin, before Ron, to her surprise, manages to stuff yet another sausage in his mouth.

"Off Pansy, go away. Bad Pansy." Draco desperately says as he tries to push Pansy Parkinson of his lap. She's ruining his appetite.

"But Dracie-pooh." Pansy giggles, not adding anything else to the sentence. On Draco's right side his best friend Blaise Zabini is trying his best not to laugh at Draco's disgusted face, and Pansy's eager, oblivious eyes.

"Don't. Say. Anything." Draco mumbles under his breath, as he get's Pansy to settle for clinging to his arm while he finish his breakfast.

"What's the first class?" Blaise ask's as he, Draco and of course Pansy exit the Great Hall.

"Potions with the Gryffindorks." Draco answers after scanning the class-schedule in his hand. He groans at the thought, bunch of half-blood, goodie goodie two shoes they are.

"Take your seats!" Snape's voice roars through out the dungeon and the student's immidiately do as he commands, after all not one of them doubts that he wouldn't think twice about poisining one of them as they slept.

"Why do we always have Potions with all the Death-Eaters-To-Be?" Harry Potter complained to Ron and Hermione, pointing over his shoulder. Hermione shrugs while placing her, very heavy, backpack next to her seat and sitting down. The first class of a new year is one of her favorites even if it is spent in a dungeon with Slytherins.

"Today we are brewing a potion known as 'The Cadena Potion' can anyone tell me what this potion does?" Snape writes the name of the potion while talking "Yes miss Granger?" he says without even turning to look at the class.

"The Cadena Potion will perform a magic chain between the two persons who drink it, sir, the chain will be one metre long. If the two persons tries to move more than one metre away from each other they will suffer through pain almost as high as the one from the Cruciatos curse." Hermione quickly answers without taking time to breathe.

"Correct." Snape doesn't award Gryffindor any points, he never does "You will be pairred up two and two and the person I pair you up with today will be your partner in this class for the rest of the week, understood?" The class nod's, and nobody complains; it's not like Snape would put Gryffindors and Slytherins together so how bad could it be?

"First pairring: Parkinson and Weasley."

Ron fall's down from his chair in shock, and Draco smirks at the thought of getting rid of Pansy even if it's just for an hour. Hermione watch Ron drag himself like was he doomed to Pansy's table.

As Snape reads the last pairring "Malfoy and Granger." Draco find himself missing Pansy all of the sudden. Hermione gasps "But sir" she begins her complaint, but it's cut off with a "No complaints miss Granger. Now get started on your potion." Snape finds it hard to keep his stern, cruel voice when inside he's doing a dance of joy. His secret passion is matchmaking, and now he has the perfect opportunity...

"You're stirring it the wrong way." Hermione half yell's at Draco. It's been long two hours according to our two main characters.

"It's moving a spoon around, how can I do that wrong you ... Gryffindork?" Draco bites back annoyed. Hermione slap his hand away from the spoon and grabs the spoon herself "You were moving it right, it says here that it's supposed to be stirred to the left. I should've known ferret's can't read!"

"Oh shut up." Draco can't come up with anything better to say, so he settles for what he has.

Snape hides a wicked smile, when he moves over to their table to perform the next step in his brilliant plan "Mr Malfoy, miss Granger. Did I just hear you stirred it the wrong way?" he questions them.

Draco reluctantly nods while Hermione shoot's him an annoyed glare, and Snape fights to keep himself from doing that dance of joy "Well well, you will have to drink it so we can see if it's still working correctly then."

"But what if it doesn't?!" Hermione ask's scared at the thought of what a incorrectly brewed potion would be able to do.

"Never mind that Granger, what if it does and we're stuck together?" Draco want's to know. Hermione's eyes widen even more.

"Then you will have to suck it up." Snape says and reach each of his students a small glassbottle which they both fill with the orange fluid and, after a deep, deep sigh, they drink it.

Silence follows. All eyes are on the pale, blonde boy and the bushyhaired girl who stares at each other trying to notice if anything's different.

"Miss Granger, get up." Snape orders "Walk to the back of the room."

Hermione almost has tears in her hazel eyes as she stands up and unsteady begin to walk. When she's more than a metre away from Draco, a horrible pain torments both of them and she instantly runs back and press herself against Draco hoping the closer she is to him, the quicker the pain will go away.

"Get off me mudblood." Draco yell's and push her away so she lands on the floor, she now has tears in her eyes.

"Mr Malfoy, watch your language." Snape warns as Hermione stands up, her legs even more unsteady than before. Not caring where she is or what can happen she points at Draco with a shaking finger "YOU! You're coming with me now, we're going to talk to Dumbledore about this!" she wraps her fingers tight around Draco's wrist and force him with her out of the Potions-classroom.

Snape chukcles silent to himself thinking "If anybody enjoys matchmaking more than me, it's Albus Dumbledore." Not the least worried about his plan.

"I understand you're concerns miss Granger, but there's nothing to do. With the time it will take Severus to make the antidote the potion will've weared off anyway. Lemon drop?" Dumbledore offers both of the young students sitting in front of his desk. Hermione sighingly hides her head in her hands, while Draco accept's the lemon drop but still frowns and scowls angry.

"This is not happening, it's not happening, it's not happening." Hermione whispers to herself, desperately trying to believe it.

"Oh shut it Granger, you have to spend a day with the hottest bloke in the school what's so horrible? Think about me, I have to constantly worry about being infected by your dirty blood." Draco doesn't foresee the foot that soon found caused his chair to fall over and him lying beneath it.

"Professor, she attacked me!" he whines at Dumbledore who looks at the boy with cool eyes "I believe you deserved it Mr Malfoy." Hermione's smirk is wicked and a good copy of Draco's.

"Now you two, please try to get along at least until tomorrow and the potion wears off. We'll take a look at your classes and I will have a bedroom arranged for you."

"I HAVE TO SLEEP WITH YOU?!" They scream at each other. "Oh euw!" they say simutaniously as Dumbledore nods to answer their question.

"Well luckily you are in all of each others classes, excpet one class. Miss Granger as your last class you have Muggle Studies and mr Malfoy you had a free perioud so it will be no problem, and problably quite educational, for you to attend the class with miss Granger." Dumbledore explains a twinkle in his iceblue eyes now.

Draco feel like he could break down in tears, and he problably would've if Hermione hadn't been there still smirking that damn smirk that he should be smirking. All though he has to admit he prefers her smirk instead of the usual eager face she has. "Now since there's only ten minutes left, you will be excused from Herbology and this gives you plenty of time to get to the Great Hall for lunch. Walk to the portrait of Emma Felton on the fourth floor and tell her the password 'Amor Prohibido' when you wish to go to your bedroom. Bye for now." Dumbledores eyes are of course twinkling as he informs Draco and Hermione of this and they leave his office.

A man dressed in black steps in soon after, and he's greeted by Dumbledores admiring words "I must say, Severus, you do marvelous work."

"I can't believe I have to share a bed with you."

"Yeah, well I can't believe I have to share a bed with you!"

"Oh come off it Granger, you know you love this." Draco smirks at Hermione as they reach the heavy doors that lead into the Great Hall and they're both struck by the same question "Where are we gonna sit?"

Hermione slowly gaze at Draco who, frowning concerned, gazes back at her but they both stay silent. Draco is having a silent argue with himself.

Half of him of course want's to sit at the Slytherin table, but that half also realise that that will mean that Hermione will see just how clingy Pansy Parkinson is, and the fact that no matter how hard he tries Draco can't get rid of her. Therefore the other half of him not want's to but can see the logic in sitting at the Gryffindor table, only one catch. It will make him seem nice, like he gave into Hermione.

He kept on arguing with himself, trying to figure out what to do "Embarrased by Pansy, or seeming nice? Embarrased by Pansy or seeming nice? Embarrased by Pansy or seeming nice?!" he groans frustrated and shake his head.

"Oh really, we'll sit at the Slytherin table now and at the Gryffindor table at dinner. Let's just get this overwith." Hermione decides with annoyance before pushing open the doors to the Great Hall and Draco hurry's after her, not willing to endure the pain of they stay too far apart again.

Hermione can feel everybody's eyes on her as she walks to the Slytherin table with her head held high, and Draco following after her with his head bend in shame. He and Hermione sit's down in between Pansy and Blaise, Pansy immidiately grabs Draco's arm and Blaise and Hermione greet each other surprisingly civil.

The food appears and Hermione's hunger help her to blissfully forget for a moment just where she is sitting. She shifts a little, she is sitting quite comfortable though.

"Hey, you have cushions on your benches." she points out to Draco, noticing the green and silver cushions "We don't have that at the Gryffindor table."

Draco's face lit up eagerly while talking "Yeah my father paid to have them, you see Malfoys have very delicate bones and we often suffer from backproblems, and it's actually quite hard to find the perfect cushion because it can't be too soft, or too hard and" he stops as he see's her raise her eyebrows in amusent.

He coughs a little "You don't? How odd, well we do." he says and though Hermione really don't want to she let's out a short laugh before continuing to eat.

When they're almost done eating the students in the Great Hall begins to stir as they all follow Ginny Weasley rise from the Gryffindor table and walk over to the Slytherin table.

"Move over big guy." she fearless tell Blaise who, because of his surprise, do as she commands and Ginny sits down and put an arm around Hermione "I heard what happend, it's so terrible. How are you so far? The ferret's not being to much of a git I hope?"

"Hey!" Draco protest before Hermione has time to tell Ginny that she's fine, but just want the day to end.

"Of course you do, you know I would to if I was forced to stay so close to that arrogant, pureblood, selfabsorbed, insufferable"

"Hey!" Draco cut her off annoyed.

"Idiot." Ginny finish shooting Draco a sickening sweet smile, before saying goodbye to Hermione and walking back to the Gryffindor table.

"Stupid Weasley girl." Hermione hears Draco mumble low, and she bites back a smirk saying "Come on, we have to get to Muggle Studies."

"Yippie yay" is Draco's sarcastic reply.

"Granger we have a ... problem." Draco says on their way to Muggle Studies.

"Yes I know Malfoy, did it take you this long to figure it out?" She is so tired of dragging him along.

"No you idiot, but... I really have to go to the loo." he doesn't blush, but he doesn't find the situation amusing either.

"You have to... Oh crap." Hermione is tempted to break down into huge sobs, that's how tired she is of this situation "Well I suppose I just have to go with you." she stares at the door leading into the boys bathroom.

"Can this day get any better?" Draco ask's no one in particular as he opens the door and look around the room. Luckily for them it's empty. To make sure they don't move too far away from each other, Hermione step's inside the stall with Draco but as he not so friendly ask's her to she turns her back to him until he's done.

Outside the bathroom they stand a moment in silence until Draco says "Let's never talk about this again."

Draco can't remember being more fightend than he is at the moment sitting in a room full of muggleborns, halfbloods and other muggle enthustiatic people while at the same time being forced to learn about them. He shudders and actually moves closer to Hermione, thinking that she at least is smart while the rest of the people in the room to him seemed... mindless.

"Sit still, I'm trying to take notes." Hermione tell Draco annoyed under her breath, because Draco keep shifting back and forth in his seat.

"Oh please you already know all of this, and the girl over there smell's." Draco whispers back slightly panicked. As the girl he has named Smelly Girl winks at him, he moves closer to Hermione but their shoulders touch and Draco panicking over touching a muggleborn jumps away from Hermione but end up falling down from his chair and land in a painfull mess on the floor.

"WILL YOU JUST SIT STILL?!" Hermione screams at him, not able to take anymore of him and at the same time knowing she can't get away from him.

"I WOULD SIT STILL IF I WEREN'T SURROUNDED BY MUGGLEBORNS AND PEOPLE WHO... WHO... SMELL!" Draco screams back from his seat on the floor.

"THEY'RE NOT LESSER PERSONS JUST BECAUSE THEY'RE NOT PUREBLOODS!"

"YES THEY ARE!"
"NO THEY ARE NOT, AND YOU'RE AN IDIOT FOR THINKING THAT, MALFOY!"

"WELL YOU'RE AND IDIOT FOR NOT THINKING THAT!"

"I HATE YOU!"
"OH TELL ME SOMETHING I DON'T KNOW, GRANGER!"

"FINE, I KICK IN MY SLEEP!" Hermione throws her notes in her backpack with force and Draco's eyes widen at the thought of spending the night with a kicking Hermione "Great." he mutters.

"... Class dismissed." the teacher small voice sounds.

Draco and Hermione don't exchange another word until they're seated at the end of the Gryffindor table as far away from any other students as possible. Ginny, Harry and Ron offers to sit with Hermione but she told them she need's to be alone.. Except she is never alone, across of her Draco is sitting watching her push around her peas on her plate with a scowl on her fice. The absolutely horrible sound of the fork dragged across the plate annoys him and he breaks the silence growling "Can't you just eat them?"

"I don't eat peas."

"Do tell why." Draco is being sarcastic, but Hermione don't notice and she begins as she so often does with "I read in a book once that peas.." she stops upon seeing Draco's disbelieving face "You thought I wanted to hear why you don't eat peas?"

"Well excuse me for trying to make this a little more bearable." Hermione quickly recovers, she had thought he wanted to know why she didn't eat peas.

"Earth to Granger there is no way to make this bearable... and if it at least had been a good story, but of course when it's you it involves nothing but a book." Draco drawls.

"Well what is a good story to you then? I snogged a boy once who just ate peas, and because he was such a bad kisser I haven't been able to eat peas since?" Hermione roll's her eyes but Draco raise his head "Really?" she simply shakes her head at him.

After studying in the library, because Hermione wanted to and Draco had no better ideas, they slowly make their way to portrait of Emma Felton and to their, they both shudder at the thought, bedroom for the night.

"Where is the stupid portrait anyway?" Draco use his wand to 'Lumos' the now dark hallway but still can't find what they're searching for.

"It's over here, next to the one of Anna Radcliffe." Hermione answers, her wand is also 'Lumosing' the hallway and she easily find the portrait.

"Amor prohibido." they say in unison and the young girl swing aside and let them enter.

The room has dark wooden panels and a proper amount of both red and green furnishing. A kingsize bed caught their attention immidiately, soon they would have to sleep there... together... Oh God!

A door lead into a small bathroom Draco speak what she thinks "However much I'd like a bath right now, I'm willing to wait until tomorrow." Hermione nods in agreement and begin to worry about their next 'adventure'... How to get changed?

She opens the closet in the room and find a pair of green boxers and a black t-shirt which she blushingly gives to Draco before pulling out her own red sleeppants with golden stripes and red top that says "Gryffindor" in golden letters. Draco look's like he's about to throw up at the sight of it.

"Maybe if we just... have our backs turned against each other." she suggests and he nods with smirk already on his face. All though they turn around, Draco can't resist the urge to sneak a peak at her long legs as she lose her robes and as quick as possible pull her sleeppants on. Without a care or a blush he change into his pj's.

"I have to sleep in the left side, or else I won't get any sleep." Hermione tell's him cooly, she's sure he watched her as she changed.

"Fine by me you odd woman." Draco snorts "Honestly who has to sleep on a certain side of the bed?"

They are now both lying in the bed, trying and faling at making themselves comfortable. Hermione tries to rest on her stomach, her back and each of her sides, but can't find just the right position to sleep in.

"I swear Granger, if you don't stop moving I will stun you." Draco has been wanting to do that for quite some time now actually.

"I swear Malfoy, I will never forgive you for getting us into this mess!" Hermione shoot's back.

A long fight about who's fault it is of course follows this statement, but it is the ending of the fight that is interesting as they both scream "GOODNIGHT!" and turn their backs on each other, miracously falling asleep.
