A/N: this is a new idea I had today... I don't know how long it's going to be, but not longer than three or four chapters, I think.

I don't own any of the HP characters.

Oh, and English isn't my first language, so if there are spelling or grammar mistakes, just remember that I'm not that good in English.

Enjoy!

Chapter 1: The Present

"Happy birthday, Remus!"

"Thank you, Harry," Remus smiled at the young man in front of him. "How are you doing these days?"

They sat in The Three Broomsticks, drinking hot butterbear and catching up with each other. Ever since the incident at the Ministry last year they had got closer, since both of them needed to fill the hole in their heart after Sirius' death.

"I'm doing great. Well, except for the fact that there is someone who's trying to kill Professor Dumbledore, and I think it's Malfoy."

Remus frowned. "You think Lucius Malfoy is trying to kill Dumbledore? Why?"

"No, I think it's his son."

"Draco? But he's a student. Why would he want to kill his HeadMaster?"

"I think he's a Death Eater." Said Harry and seemed bitter. "But no one wants to believe me."

"Well, that's because it sounds… odd, that Voldemort would let a sixteen year old join his army."

"Great, you don't believe me either." Harry crossed his arms and looked away.

"I'm sorry, Harry, but it just-"

"Yeah, I get it. It's odd."

Remus didn't know what else to say, so he just kept drinking his butterbear in silence, while Harry was looking at the rain outside.

After a few minutes of silence, Harry raised his gaze and said quietly, "Do you ever wonder what could have happened if…"

"If he was still here?" Remus completed the sentence, and when Harry nodded he said, "Yes. I think about his everyday."

"Me, too," whispered Harry sadly. "I miss him."

Remus sighed and said nothing. He hated to think about it, and talking about it was even worse. It's not that he hadn't accepted what had happened. He knew Sirius was not coming back. But talking about his made it more real and it hurt him more than anything.

"I got you a present," Harry suddenly said, and took out a small package from his schoolbag.

"Harry, you really shouldn't have." Remus said, but Harry insisted that he will take it, so Remus gave up. He looked at the package that was very small and seemed to be empty. "What is it?"

"It's a spell. I got it from a gift shop down the street. It was Hermione's idea, actually, and I thought you might like it."

Remus examined it with interest. "What does it do?"

"It can bring you back to relive one day from your past, any day you'll choose. And it won't have any effect on the future." Harry replied with a grin on his face. He seemed pleased with himself.

Remus stared at him with shock. "Are you serious? Is that even possible?"

"Of course it's possible. And all you'll have to do is just pick one happy day you want to relive, and open the bag. But do it when you're alone so no one would be able to interrupt in the middle."

"Harry, are you saying that if, for example, I'll choose to go back to a day from my childhood, I'll go back to being a child?"

Harry nodded. "Well, yeah, that's the idea. But it would be only for one day."

Remus stared at the miracle in his hand. "I- I don't know what to say…" all the possibilities suddenly opened for him, he didn't know what to do. "Thank you so much! Does it work?"

Harry's grin grew wider. "Yeah, it does. I tried it myself, last week. I went back to a day with…" he sent a worried glance at Remus, "with my parents. It was amazing. Even though I… well, I couldn't really speak, but it was great just being around them."

Remus smiled sadly and nodded. "Yeah, it must have been very special. And it must have cost you a fortune. You really shouldn't have-"

"Remus, shut up. It's a gift, okay? Just… just enjoy it."

And he did. As soon as he got to his apartment he locked the door and sat on the couch, staring at the paper bag.

There were so many days he wanted to get back to; he didn't even know how to start to choose just one of them. There was the day when his three friends, Sirius, James and Peter told him they had figured out his secret, and that they hadn't care at all. The feeling he had that day, to know that his friends accepted him, was the wonderful feeling in the world.

There was the day when he and Sirius moved in together after graduation. Living with him in Hogwarts had been great, but having him all to himself at their flat had been even greater.

But the day he longed for the most was the day Sirius had told him he loved him. It had been in their fifth year at Hogwarts, after a long time of dancing around each other without revealing their feelings. And then, one day, Sirius had told him he loved him. Remus had never felt that happy.

He smiled dreamily at the memory of the to of them kissing for the first time. What a wonderful day.

Without another thought he opened the bag, thinking about that day. Tingling of magic went through him and warmth filled his whole body. He started to feel dizzy, and his head was spinning fast. He tried to stand up, but he stumbled on his feet. Right before he hit the floor he felt himself disappear.
