In the morning, Hermione arrived at the common room wearing Malfoy's tie.

-'I warn you, the boys are being idiots again' sighed Ginny rolling her eyes.

-'Hermione, can't you just give up Malfoy's dare ?' asked Harry.

-'And burn his tie ?' added Ron.

-'It's just a tie ! I can do it and I refuse to give up against Malfoy'

-'Let her play, she'll win for sure ! We all know that Malfoy won't show up with the tie !' said Ginny 'He's too disgusted by our house's colors'

-'Hermione, did you think about the teachers ? Aren't you breaking a rule by doing that ?' asked Harry.

-'What are they going to say ? You're their best student !' claimed Ron.

-'They won't even notice !' said the redhead girl.

-'I doubt that it counts as breaking a rule' added Hermione 'And being one of the best student as nothing to do with this'

The boys sighed loudly and gave up. She wanted to play with the Slytherin and they couldn't do anything about it.

Meanwhile in the Slytherin dormitories, Draco was putting on the tie.

-'How do I look, guys ?'

Goyle pulled a face and Theodore barely looked at him. He clearly preferred reading his book. Draco turned to Zabini.

-'Mr Lovegood, something to add ?'

-'Don't call me that !' snapped Blaise 'And you look as horrible as always'

-'Well, you three, you're really useful friends' said Draco rolling his eyes 'Let's go to the Great Hall'

They all got out of the dungeons and on their way they saw the Gryffindors from afar.

-'Oi Granger !'

Draco waved an arm and showed her the tie. She showed him hers and she suddenly had an idea.

-'Malfoy ! Truth or dare ?'

-'Dare, obviously !'

-'Go sit at the Gryffindor table !'

-'What ?' said Harry and Ron in unison.

-'Okay but you have to go at the Slytherin table then !'

-'Have you lost your mind ?' asked Blaise.

-'Deal !'

The two groups entered the Great Hall. Hermione and Draco switched places. The Gryffindor sit between Pansy and Blaise.

-'There's definitely something wrong with you two' said Zabini.

-'We already knew there was something wrong with Draco' sighed Pansy. 'But you Granger, I thought you were more or less sane'

-'I'm sane. It's not because I'm playing a game with -'

-'With Draco Malfoy. You have to be as insane as him to play. He won't let you win. Believe me' said Blaise.

-'I won't let him win either'

Draco sat down next to Ginny and Dean Thomas.

-'To be honest I thought you wouldn't dare to wear the tie' admitted Ginny.

-'Never doubt of a Malfoy'

Ron and Harry both rolled their eyes while owls swooped in the Great Hall. An owl stopped in front of McGonagall.

-'Finnigan, the letter you made me write has arrived' said Malfoy.

Seamus simpered waiting for the professor's reaction. The headmistress finished reading and burst out laughing. Everybody gave her weird looks except the older students who knew about Draco's letter. But still it was disturbing to see the stern woman laughing.

Once the Transfiguration teacher had finished laughing, everyone went back to eating their breakfast.

The rest of the day went well. The teachers didn't seem to notice the ties swapping or at least didn't say anything about it. They had one class left. The Slytherins and the Gryffindors had both History of Magic. As soon as professor Binns started talking, Hermione started writing.

Draco thought this day was becoming boring. He wondered if it was the right time to bother Granger. He took a piece of blank parchment and his quill.

The parchment was flying around Hermione's head and Binns didn't seem to notice it. She caught the paper and read it. "Truth or dare ?" She turned around to see Malfoy's grinning face. She sent a paper back. "Dare" His smile grew even bigger when he saw her answer. He quickly scribbled what he had in mind. "Get rid of everything you've written so far. You'll follow History of Magic only through my notes" When she read her dare, she couldn't help but make a rude hand gesture at Malfoy. She sent another paper. "You better pay attention at what professor Binns says then ! And for how long should I borrow your notes ?" He replied quite quickly. "Let's say a month" Hermione almost swore aloud.

-'You're alright ?' asked Ron.

-'I don't write notes anymore'

-'What ?'

-'Malfoy dared me to. For a whole month'

-'What was the dare exactly ?' asked Harry.

-'I can only follow History of Magic with Malfoy's notes'

-'In other words, he's going to work for you' said Ron.

-'He's doing that because he knows that his work won't be as good as mine and he knows that it'll get on my nerves'

-'Still it's like he was working for you' said Harry.

-'What about us ?' asked Ron 'If we can't borrow your notes anymore, we're doomed'

-'Well we could still borrow yours even if it won't be really yours' said Harry.

-'Sure' she said 'Or you could work for once'

Harry and Ron looked at each other and both knew that it wasn't going to happen.

Hermione spent the rest of the hour doing nothing. She sometimes checked that Malfoy was taking notes. Now she was waiting for him to get out of the classroom.

-'Why are you waiting for him ?' asked Harry.

-'To borrow his notes and giving him the tie back'

-'You want us to wait with you ?' asked Ron.

-'No, you can go. It won't take long'

He finally got out with Blaise.

-'Oi Malfoy !' she said. They looked at her confused. 'You aren't forgetting something ?'

-'You want the notes now ?'

-'What notes ?' asked Blaise.

-'I'll explain you later' said Draco 'Here, you'll give them back tomorrow morning ?'

-'Sure but wait'

She put the parchment in her bag and she removed her tie.

-'Here'

-'I'd almost forgotten. Such a shame I was getting used to you with my tie'

-'Green doesn't suit me. Give me mine back'

He removed his tie too and gave it to her.

-'You're done ? We can go now ?' asked Blaise.
