Thanks to everyone who has read this fic so far. I only posted it yesterday, and already I have had 76 people read it. Special thanks to the two people who reviewed for me (LIGHTNSHADOWS and HeartsGlow). Thanks again to HeartsGlow for pointing out the error in the summary (now fixed). And my heart was warmed by the sight of all you people who added this to your story alerts!

Enjoy and please review!

Half way to the Transfiguration classroom, Harry stopped. Something was missing. His bag felt too light. That was when he realised that he had forgotten his books for the classes that morning. He began to walk towards the Gryffindor tower, knowing he would have an extra ten minutes this morning before class started to allow the students to calm down a little before the professors had to deal with them.

He thought about nothing in particular as he walked back to the common room. Subconsciously he muttered the password to the Fat Lady before wandering up the stairs to the 5th year boys' dorms. He busied himself for a minute or two, trying to remember exactly which books he needed for which classes, before he was startled out of his musings by a tapping sound at the window. He looked up, and the owl outside stared back, flapping its wings in a steady rhythm to keep itself aloft. He opened the window, and the owl flew in and dropped a letter on his bed, before heading straight back out into the sunlight.

Harry stared at the letter, unsure of what to think. This owl hadn't arrived much later than the post, and he assumed that it could have made it to the Great Hall in time if it had really wanted. This meant the letter was from someone who didn't want him reading it in front of the other students. His mind briefly flicked to his godfather, Sirius, before remembering that the Ministry of Magic had recently begun searching for him, and Sirius was currently on the run. He wouldn't have sent a letter, because there was too much chance it might be intercepted, and the Ministry might find him. That took away the only option Harry could think of.

The envelope was plain white, and nothing about it seemed unusual. He knew if Hermione was here, she would have subjected it to all kinds of tests to make sure it wasn't someone out to get him. He didn't care, he decided, as curiosity washed over him. He reached for the envelope and pulled out the letter. He felt the familiar cool feeling of magic wash over him, but chose to ignore it for a moment in favour of the letter's content. The writing was beautifully cursive, written in a green ink that seemed to make each word glow as his eyes passed over it.

Dear Harry,

The greeting caused him to pause momentarily, and his eyes flicked to the end of the letter. There was no name, and Harry was left wondering why someone who chose to remain anonymous would address him with such familiarity. He started reading again.

Dear Harry,

Happy Valentine's Day. I think I should apologise now for the spell you no doubt felt, activated when you touch the letter. It was a prank, initiated to amuse my peers, and to remove suspicion as to why I chose to write to you. The effects of the spell are simple. Your hair and robes will turn pink, and it will wear off around midnight tonight. I hope you find it as amusing as they do.

I bet you are wondering who is writing to you, and why. I cannot answer who, but I have been admiring you from a distance for some time, and want to get to know you better. In truth, I wish to be your Valentine, but it is difficult to share that bond when you cannot know who I am. Not yet.

I really hope you enjoy your Valentine's Day, and although I did not do anything as mushy as buying you flowers and chocolate (I shudder just at the thought!), I hope you understand I will spend the day thinking of you.

If you wish to respond, there is one owl in the owlery who will know where to take the letter. He has a tag around his left leg. The tag is the exact colour of the writing in this letter, and if you hand him your reply and say 'To your master', he will know where to take it. I do not expect you to reply.

Love (although I do not yet know if that is what I feel),

Your Valentine

Harry stared at the letter in shock. He was contemplating disbelief, and throwing the letter in the nearest bin, but something in the tone of the words struck him as sincerity. He tucked the letter into the pocket of his robes, which he noticed were definitely now a shade of pink to rival that morning's breakfast, and finished packing his books into his bag. He knew it would try to be useless to counter the spell, and he relaxed, slowly, deciding it would be better to chuckle with the other Gryffindors over the state of his hair and outfit than to let it get to him and spoil this particular day.

He laughed quietly, understanding now that whoever this mysterious person was, they knew the prank would amuse rather than distress him simply because he was around the Weasley twins all the time. He checked his watch, and then sprinted back through the portrait hole and down to Transfiguration, where his best friends looked at him in surprise and barely concealed amusement as he slid into the seat next to them.

-o-o-o-o-o-

The day passed with little incident for Harry. He managed to make it to all his classes, and after explaining the prank with the letter (telling Ron and Hermione that he had thrown the offending piece of paper in the bin as soon as he realised its effects), everyone had a little laugh at his expense. As the day wore on, he did begin to find it a little disconcerting how many girls walked up and told him they liked that particular shade of pink, and his friends watched with glee as his blush rivalled his hair and uniform.

The twins made the day considerably easier for Harry, when at lunch time they noticed the charm. They decided to imitate him, changing their hair so it was bright pink, and spelling their uniforms pink but with an added twist. Every few seconds, silver hearts streaked diagonally across the twins uniforms, in perfect timing.

Draco sat and glared from the other side of the room as the Gryffindors applauded the Weasleys' spell work. He was happy, in a way, that Harry had taken the prank so well, and that the twins were looking out for him and making Harry's day brighter, but he couldn't help feeling peeved. He knew that if he owned up to being the one to turn Harry pink, the Slytherins would laugh at him. If the prank hadn't worked, no one need know who initiated it. It was for this reason that Draco spent lunch slumped in his chair in a very un-pureblood posture, trying to plan something else so that Blaise wouldn't complain at him later. He was so caught up in his thoughts that he hadn't even noticed the whole of his house sitting as far from him as possible, so they couldn't be tainted by his slouch.

He needed to think of something!
