As they arrived in Magnolia, Natsu was quick to go off the train.

"Yes! I'm out of this monster!" he shouted, then he remembered he was with Lisana

"Sorry Lisana"

Then, he thought of something.

"Lisana, could we go back to our hut from when we were kids?"

"Yes of course Natsu, that'd be fun, I haven't gone back there since I came back"

And so, the both of them started their way toward there.

As they arrived, Lisana quickly noticed a gravestone

"Natsu, this gravestone mine?" she asked hesitantly

"Yes, it is"

"I thought it was at the cathedral" she continued confused

"I also built one here because I knew you loved to watch the sunset from here"

Lisana could see the sadness in his eyes just remembering these events.

"Natsu, don't think about it anymore, I'm here now" she said wrapping her arms around him.

"It was so hard when you disappeared" Natsu said, tears forming in his eyes

"I know, but I'm here Natsu"

"At first I didn't believe it, I couldn't believe it, you were, you were so important to me, I couldn't imagine the guild without you" this time, he was crying

"It's okay Natsu, you can cry as much as you need"

"Then, I was so devastated I broke down as soon as someone would talk about you, because of me, nearly everyone at the guild stopped talking about you"

"Shhh, it's okay Natsu, now I'm back here and everything'll be okay"

"When I first so you in Edolas, I was so happy, I was sure it was you, but then, when you said you weren't our world's Lisana, I was even more devastated, I had hope for a few minutes and it was shattered."

"I'm so sorry Natsu, I shouldn't have done it"

"No, no don't blame yourself, it's not your fault, I promise. And don't worry, even if was desperate at that moment, the moment when I saw you back in Earthland and you hugged me was so much more intense that anything else, I don't care if you lied when we were in Edolas, I understand why you did it, as long as I could see you again I don't care."

They stayed in silence for a few minutes, still hugging each other close.

Feeling Lisana close to him, Natsu finally gave her a soft and loving smile before returning the embrace.

After a few more minutes like that Natsu seemed a little hesitant and slowly got out of the embrace.

"Is something wrong Natsu?"

"It's just, I think I should tell you something important about dragon slayers"

"You can tell me anything Natsu"

"We dragon slayers inherit certain things from dragons, as dragons, we can only love one person, the only one who can become our mate"

"Am I your mate?"

"You are the one I love, but not my mate for now"

"What would make me your mate?"

"I'd have to mark you as my mate though-"

"Then do it"

"Are you sure Lisana? I mean, if I mark you, it would mean we'd be together forever" He asked a little confused at her reaction

"Yes I'm sure Natsu, I love you, and I know you love me too" She answered determination visible in her eyes.

"Then I'll do it, but I have to warn you, it will hurt you a little bit."

"It's okay, I know you won't hurt me too much"

He got closer to her, wrapped an arm around her and really gently cupped her chin with his other hand, giving him access to her neck. He started to softly kiss her neck, then he pierced her skin with his fangs, making her yelp from the pain. Though, after only a few seconds, he started to lick it sending a bit of his magic through it to close the wound quickly. The pain quickly disappeared, and she started to feel really comfortable close to him.

Though, when he pulled back, she also felt exhausted suddenly.

"Lisana, are you okay?"

"Yes, it hurt a bit at the beginning, but I'm fine now and I'm glad I did it"

"I'm glad to hear it"

"Though, I'm exhausted suddenly"

"It's normal, I'm exhausted too, that's a normal consequence of the mating, so I think we should go to sleep"

"Yes, I agree with you"

And so, the both of them entered the hut and laid down. Lisana resting her head on Natsu's chest, the both of them wrapping their arms around the other.

They both fell asleep really quickly together.

As she woke up, though, Lisana started to feel a sort of warmth from the place where Natsu bite her neck the previous night.

She saw that Natsu was already awake

"Good morning Lisana" he said, kissing her softly

"Good morning Natsu" she answered after the kiss

"I could definitely got used to waking up next to you"

"I think I'd like it too. Natsu, I don't understand something"

"What is it Lis?"

"I feel a sort of warmth from the spot you bite on my neck last night"

"It's okay, don't worry, I'll explain it, but first, come with me"

"Okay"

And so, he led her outside toward the lake

"Look at yourself in the water"

She did and quickly saw something on her neck. Looking closer, she could see a mark representing a red dragon.

"Is this what you meant by marking?"

"Yes, it's my mating mark on you the mark that shows that I'm yours forever and that you're mine." He said, smiling softly at her

"Why does it feels warm?"

"To create it, I put some of my magic into you, that's why it feels warmth it's as if you could feel my magic through it, and, if you focus enough on me, you'll be able to feel this warmth in your whole body. The mark also makes you immune to my fire"

She was processing everything she learnt from it.

"The only bad point is I won't be able to surprise the whole guild with our relationship, they'll know as soon as I'll come in the guild."

"I got an idea!" Natsu answered, and then, he wrapped his scarf around her neck, effectively hiding the mark.

She was dumbstruck, she had never seen him take his scarf off.

"Now climb on my back, it will be faster to reach the guild"

"Okay, but you better not drop me" she joked

"Don't worry, I would never hurt you", he said lovingly

"I know Natsu, I was just teasing you" she giggled

And with that, she climbed on his back. He quickly began to run towards the guild, propelling himself with his magic.

As they were running through Magnolia, they got surprised looks from a lot of inhabitants, making both of them laugh. They could be heard from afar before they even entered the guild. Though, when they entered, everyone looked at them surprised, seeing Lisana on Natsu's back, the both of them still giggling, but what shocked them the most was to see Natsu's scarf around Lisana's neck. Since he arrived in Fairy Tail around seven years ago, they had never seen him without his scarf.

The both of them realized what they were doing and blushed. Natsu gently set Lisana down.

"Lisana, why do you have Natsu's scarf?" Lucy asked her

"He gave it to me because I was cold and forgot to take it back" She answered "Though, I think I should give it back now"

And so, she slowly unwrapped the scarf from her neck to give it back to Natsu. As she finished, everyone in the guild gasped, seeing the mark on her neck, Gajeel and Wendy were even more surprised.

"Lisana, what's this mark?" her sister asked

She blushed nervously and didn't answered immediately.

"It's Natsu's mating mark, he marked her as his mate" Gajeel said as Lisana was still silent.

"What did you do to my sister?" Elfman asked angrily

"Calm down big brother, he did nothing wrong, I was the one to ask"

"But what does a dragon slayer's mark means?" Lucy asked

"It means that she'll be my mate and we'll be together forever" Natsu answered grinning, wrapping an arm around Lisana.

Lisana looked at her sister, who smiled gently at her. She was finally happy, she had gotten what she had dreamt of since she was a child.
