A/N: Hello, there. Welcome to 'Unmissable Affection'.

A few weeks ago I randomly decided to write a Hermione/Severus Fanfiction. I started writing this for fun, not even thinking about that I could upload this a day. But well, as you can see a day I uploaded a little 'Preview' of this story - and as it seems - a lot of people liked the idea of the story.

The story starts somewhere during Harry Potter and the Half-Blood Prince. Please notice that a lot of things won't be like they are in the books. A lot is changed in this Fanfiction and won't be like it is in the Original Stories of J.K Rowling.

If you have an idea and want me to include it - feel free to write me. I am happy about every 'request'.

Many thanks to my great beta reader bluegirl1750.

Disclaimer: Harry Potter belongs to J.K Rowling. I do not own Harry Potter or any characters of it and I don't make any profit. I am just playing in her Sandbox. ;)

Chapter 1 – An unsuccessful attempt

"Harry, you need to tell Professor McGonagall about this! You know what will happen if you don't!"

"No way, Hermione! Can you even imagine what she'll do if I tell her or she finds it out? Months of detention? Getting kicked out of school?"

"It'll just get worse if you don't tell her. You know that."

As Harry, Ron and Hermione made their way to the 'Defense Against the Dark Arts' classroom Hermione had just started another attempt to talk to Harry – obviously without success.

A few weeks ago Harry had found a special book of 'Advanced Potion Making' which isn't like the others. The book is full of added handwritings. The former owner seems to know a lot about Potions because it tells Harry exactly what to do. And, like the 'crown' of it, it had some spells in it that Hermione had never heard of.

Of course Harry refused to talk to Professor McGonagall about it - something Hermione could not understand. Besides the fact that Harry now always received the best marks in Potions by 'cheating' and Hermione's work- which was excellent as always- didn't earn any attention, there was something else that made Hermione anguish. Was this a normal book, or did it maybe have the ability to do something unwanted?

Hermione and Ginny both were really curious about who the owner of this book was. Or maybe is?

'It has to be someone who is really good in Potions' they both assumed but neither Ginny nor Hermione supposed who it could be. Besides, there were a lot of people that could come into consideration.

Soon they arrived in front of the Defense against Dark Arts classroom and entered.

Their professor was still not there – something they were all grateful to see.

Any Hogwarts student could have figured out who the next professor in this room would be. The classroom was dark, all the windows were closed, and there were only a few spots of light that kept the room from being completely dark. Before they could reach their seats a Gryffindor student waved at them. Or more like only one of them.

Hermione recognized her. Ron had mentioned her before when they were doing research in the library.

Lavender Brown.

To Hermione, she acted a bit strange which led to her not liking the girl. Since their first Potions lesson she seemed to be attracted to Ron. Whenever she could, she looked at him, smiled at him and gave him compliments.

Before, Hermione thought that Ron was attracted to her – but now he barely spent any time talking to her.

'Another one who gets a girlfriend. Another one who isn't going to stay forever alone.'

Harry was getting closer to Ginny lately and Hermione feared that during her time left here at Hogwarts, she would not get her first kiss or even a boyfriend.

The door suddenly cracked open and the unpopular Potions Master – Severus Snape – walked into the dark room.

Today he looked really different. He was paler than usual – and the professor is normally pale as it is. His presence was dark and he didn't make eye contact with any of the students. He sat down and wrote something on the Parchment in front of him. She thought she saw a small smirk on his face, and then he started talking – without looking in the students' direction.

"Make two rows and attempt to jinx the other without speaking."

When no one moved, he growled even louder: "Go. NOW!"

He really was in a much worse state than Hermione had suspected.

'What the hell's been going on with him lately? I know it's not my concern but… doesn't he have anyone who is there for him?'

Harry touched Hermione lightly on the arm and she nodded as an answer.

They made two rows and stood still as they saw their 'enemies'.

Hermione had Tracey, Harry had Hannah Abbott, and Neville had Draco.

'This definitely won't end well' Hermione thought as she saw the pairings.

As the first few jinxed each other nothing bad happened, despite some 'Ouch's and stumbles, but when Neville was standing face to face with Draco the whole class was looking at them.

Professor Snape rose from his chair, visibly curious about what would happen next.

Neville was not bad in blocking spells and Hermione knew that. He could manage this. It was more his personal state that got him into these situations every time.

Draco made the first step and Neville blocked his spell perfectly.

But then something happened that no one expected.

Draco mumbled a spell that Hermione never heard before and before Neville could even react he flew into the air - then against the stone wall on the opposite side of the room.

Everyone in the room was shocked and couldn't move, except Professor Snape and Hermione.

His reflexes were the best Hermione had ever seen. Faster than her, he was next to Neville who was lying on the floor.

Neville let out some soft cries and noises, unable to control them.

"Mr. Longbottom? Can you hear me?" He didn't answer.

Professor Snape really seemed to be alarmed.

Hermione sat down next to Neville and as she did she saw blood running down from his side.

At first she was shocked but then stopped in her tracks and pressed a hand over the wound, and said alarmed:

"Professor! He is bleeding!"

Professor Snape hurried to her side, swinging his wand in alarm, and mumbled an "Out of here!" addressed to the staring students and then everything happened pretty fast.

The students hurried out of the room as he demanded. Only Hermione remained where she was.

She continued to press her hands against Neville's wounds – which seemed to get worse and worse – then she suddenly felt a cold hand on hers. It was his hand, but he did not seem to mind the contact between them at all. He just pressed their hands harder to the wounds as if he thought they were going to explode any moment.

Then a few elixirs flew through the room, and he broke the contact between their hands to take them.

He barely looked at her before handing the elixirs over to Hermione, hoping she would know what to do. 'Of course she knows!' Severus thought. 'She is one of the best students.'

He was right- Hermione knew what to do. One elixir she held to Neville's mouth to make him drink it. The other she put on his wounds.

Neville was screaming more and they both – Professor Snape and Hermione – hoped it would stop soon. But this didn't happen.

Hermione looked into Snape's face and for a short moment she saw an emotion that she had never seen before.

"Move back Miss Granger."

She did as she was told, even if she was a bit puzzled.

Then she heard him say:

"Vulnera Sanentur. Vulnera Sanentur. Vulnera Sanentur."

She had never heard this spell before. What was it? And what did it do?

Before she had the chance to ask the professor, he was no longer standing next to Neville. It was now Madame Pomfrey.

A cold hand gripped her shoulder, taking her back and escorting her out of the room which was where Neville lay– covered with blood.
