A/N: Hey Guys! So this is the first fan fiction that I have ever written, so I hope it's okay. It's about Meliodas and Elizabeth from Nanatsu No Tazai, I just think they are so cute. I know that the story isn't completely faithful to the manga, as I changed some parts, but I wrote this before some of the new chapters came out so hopefully it's still okay. Thank you for reading and let me know what you think!

**Update: So I wrote this about a year ago and I'm going to do some edits to hopefully make it better because when I read it, I just cringed so much and I feel like I need to do something to help myself feel better (and hopefully it wasn't too terrible in the first place).**

I do NOT own Seven Deadly Sins.

-My Only Sin-

"We all die someday, but as long as someone keeps a person's wishes alive, they won't die. No matter how much you bleed and even if your tears run dry, you stick to it...that's what it means to be a knight"

~Meliodas-Seven Deadly Sins

Chapter 1

I look around the dining room. All the paintings and tables are in order; granted, half of the other part of the castle is missing, but this half looks nice enough to live in. I can hear the low rumble of the guards and town's people working on the repairs. The more and more I hear, and see—and feel—the more it makes me happy that I'm finally back here. I can even feel tears sting at the corners of my eyes as the memories of my journey come flooding back..

"I never thought I'd see the day," Margaret says.

"We're all finally back together," Veronica joins. I smile in agreement.

"Elizabeth," my father starts, "Meliodas, and the other sins, are leaving this morning. I do not want you going with them."

"What?" I scramble to my feet. Sir Meliodas is leaving? "This is so sudden! I-I must say goodbye!"

"No," my father stands up to face me, "I forbid you to see him. Meliodas knew this was dangerous and he decided to leave on his own—" The ground starts to shake and interrupts my father's thought.

Paintings fall off the walls and our table shakes, knocking some of the plates onto the floor. I rush to the window. At first, all I see is green. But when my brain finally realizes what is happening, I bring my head to look up.

"Elizabeth!" A voice calls from the top of Hawk's Mom. Meliodas hops onto the ladder that descends from the back of Hawk's Mom, landing right in front of me.

"Sir Meliodas!" I smile at him.

"I forgot one really important part of the promise I made to you," He counts on his fingers to six, "I promised to find all seven of the sins with you - but we only have six," Meliodas laughs and sticks out his hand, "You wanna come?" those green eyes of his burn brightly back into mine, they are so incredibly irresistible.

"Yes!" I glance back at my father, "Take care of yourselves," I call.

"Ellie!" My sisters call after me, but I wrap my arms tightly around Meliodas. We swing up to the top of Hawk's Mom's back. Everyone is there—Diane, Merlin, Ban, Gowther, and King—and I'm so overjoyed to see all of them. Hawk jumps onto my shoulder, still a smaller version of himself.

"Elizabeth! I'm glad you're here, it's not the same without you," Hawk says; I smile and pat him on the head.

"Sorry we're late," Diane says.

"We've never kidnapped a Princess before," King laughs nervously. I turn toward the front of Hawks Mom, looking off at the land with nostalgia, remembering when I had first met the Captain of the Seven Deadly Sins, and the sweet smell of the air as we rode off to our adventure.

Meliodas turns to Merlin and asks her about all those years ago. She juts gave him a smile. I am too distracted to listen to the rest of their conversation. I am too filled with excitement and fear for what the future holds for us. But I know, I know everything will be fine as long as we're all together. I know everything will be fine, with Meliodas by my side.

Merlin takes Meliodas inside so they can discuss whatever it is they need to, while the rest of us wait patiently outside. I breathed in the cool air, the wind rustles through my long yellow dress. I know I should probably change into something more suited for an adventure, but I had left with such haste that I hadn't any time to pack even the simplest of things.

"Excuse me?" I turn to Diane, "Diane, do you happen to know where the uniform Sir Meliodas gave me last time is?"

"Oh that perverted thing," Diane rolls her eyes, "Yes I know where it is. Elizabeth, do you want something else to wear? You know, you don't have to wear it…"

"It's no problem, I should be fine with what I was wearing last time, thank you, though…" I smile.

The tight fitting shirt and short skirt fit me just as well as they had the last time. It was embarrassing to admit, but I didn't mind the clothes that Meliodas gave me. They made me feel less like a princess and more like part of the team. Useless as I was, I still wanted to be a part of the team. And wearing a yellow dress was not the best way to start out.

I'm most happy that we're all back together, but I do wonder what will happen when we do find the seventh sin—Sir Escanor? Will we remain friends? Maybe they'll go back to being the Knights of Liones and I'll go back to being just the princess. Who is good for nothing but getting in the way, I turn to King. I haven't heard much about Escanor, but I know enough to realize that thing won't stay the same once we find him. Come to think of it, I don't really know that much about Merlin either.

"Um Sir King, Diane, could you tell me what Lady Merlin is like?" I've never really heard much about her; only once from Gowther very briefly. King shrugs at first, then he turns to think for a moment, as if they can't find the words to describe her.

"Well, she's an expert in magic," Diane answers, "Calling her a witch isn't really the right word, but something along those lines."

"Yeah, Merlin's probably got the most magic of us all," King adds. "Though, you could say she's kind of like the outsider among us. Always sneaking off and kind of having an agenda that only she knows about. But she's still one of us, and I wouldn't go about asking her to her face about any of this. "

"Well, I can't wait to get to know her better," I smile at the thought, "So, what exactly are Lady Merlin and Sir Meliodas talking about?"

"The Captain and Merlin are conversing on what happened ten years ago," Gowther says.

"What happened?" A nervous glance shifts through the group, and the question hangs in the air for a while. I quickly dismiss it with a wave, "Never mind. It was rude of me to ask." I can tell I shouldn't have asked because although they seem to relax, I can still feel the tension of the air around us. It's quiet for long while, then King breaks the silence.

"It feels so good not being wanted criminals anymore," He sighs, propping himself on Chastiefol, "We can walk around freely, no bounty on our heads."

"Yeah, but I'm sure a lot of people in Liones will still be afraid of us," Diane said. I look down at my hands, not sure what to say to make her feel better. I am sure that the kingdom will welcome her once they know how great of a person she is. But even I know that they won't be used to having her around right at the beginning.

"Hopefully they'll see what kind people you all are," I smile weakly, "You haven't done anything wrong."

"But that's not how other people have thought of us for the past ten years," King says.

"Perception is everything," Gowther lifts his hand, "And everything is more powerful with fear instigating it." All of us give Gowther a weird look, but soon dismissed his comment. I find him quite weird at times, but in all honesty he is still a wonder knight.

Diane heads inside to get some food, and Gowther follows closely behind her. King decides to take a nap on Chastiefol until things pick up around the Boar Hat. I'm not really sure how long Meliodas and Merlin plan to talk, and I'm not really sure what to do until they're done. I stand blankly for a moment, trying to think of something I could do to be of use.

I head into the kitchen, taking an order from Hawk along with me. I know my cooking isn't as good as Ban's, in fact, I've never really cooked before, but Hawk doesn't seem to mind. He says it is much better than anything Meliodas could make, which makes me smile.

I look over at the three sins that keep my company in the tavern. I wonder how anyone would think that they would plot to overthrow the kingdom. They are all such kind people, and I have come to cherish them all as dear friends. I know that they have all have a sin, and are branded with a mark too, but we all have our fair share of wrong doings. And I don't see why that should prevent them from being paid the rightful respect that comes with being a Holy Knight.

For all of them to be so different, and yet get along so well, it's anything but evil. I just hope the rest of Liones can respect them like they once did. I know I do.

Meliodas and Merlin come back to join the rest of us. Merlin has a rather somber look on her face, and Meliodas seems in higher spirits than he did before.

"Captain, you seem different," King turns to Meliodas. "Did Merlin say something?"

"Yeah," Diane narrows her eyes, "What's going on?"

"Merlin said that she will be able to return my full power. Which she's keeping secret for the past 10 years," Meliodas smiles. Merlin stands behind him, looking like a scolded puppy; but she doesn't keep that attitude for long. She places her hand on her hips.

"Since we're all back together now, and Escanor is bound to make a show sooner or later, it's time we get down to business," she looks around at us. "We need to get your sacred treasures back, and the Captain's broken sword."

It seems to me there is a lot of stuff we need to do, and a lot of business that needs to be taken care of. I don't question them; though, instead I stand waiting for an explanation from Meliodas.

"What's the rush?" King asked. Meliodas turned to face us, his expression heavy.

"The Coffin of Eternal Darkness. We need to find it and make sure it stays closed. Before the Demon Clan can be resurrected. And I don't think time is on our side."

. . .

Ever since the Battle with Hendrickson, we've seen a lot of people, especially Holy Knights, coming into the Boar Hat. All of them have different reasons, the most common is so that they can meet the heroes of the kingdom, but others juts followed the crowd, and others just stumbled in here by accident. Either way, Meliodas is determined to make sure that everyone has at least one drink. Tonight is one of the most crowded nights that we've had in a while.

"Hey Diane!" Meliodas calls, "Could you set up more tables outside?"

"Anything for you, Captain," Diane smiles.

Since Diane returned to her normal size and can't fit in the tavern anymore, she's been waiting outside and greeting guests as they enter. She grabs extra tables and chairs and sets them up outside. We still don't have enough to seat everyone and some people have to lay down blankets in the grass.

I have gotten much better at waiting tables, and can safely get people the right order without tripping over my own feet. King is in the kitchen making food, since Ban isn't here, and he's not half bad at making meals either. Meliodas serves drinks behind the counter, smiling and laughing like he belongs just like everyone else.

Gowther is helping me bring orders to tables, and he even insists on wearing the uniform Meliodas gave to me. Merlin helps Diane out with the greeting customers, and she seems to be a natural people person so it works in our favor.

I look around and smile. This is exactly the kind of joy I wanted to bring back to the kingdom, everyone together, and happy, sharing drinks, and food, and exchanging funny stories. It's a bit strange, though. The Holy Knights sit and talk with the Sins, but the townspeople still seem wary. I know they weren't at the battle to witness the heroic sins in action, but that shouldn't matter.

"Elizabeth," Meliodas calls, "Could you look after things for a second? I need to go talk to someone."

"S-sure!" I smile. Meliodas pats me on the head, then he leave to walk outside.

"Okay, the next order is ready!" King calls from the kitchen.

Two men at the bar, who must have ordered the same thing, start to argue about who ordered first. Then they start to fight, fists go flying and even some cups are thrown. People gather around to watch; I just duck quickly out of the way.

"Ouch," a little girl cries. One of the men must have accidentally hit her instead of the other man, but neither one seems to notice.

After letting it go on for a little while longer, King makes a disgusted noise with his mouth and walks over to the two of them. Using Chastiefol to pick them up by the collar of their shirts, he seperates them and nring steh fight to a halt.

"Break it up you two," King says, having one person on each side of him. "The Captain's not going to happy if you wreck the place, I mean anymore than you already have."

The two look around at the mess they made. Chairs are spread askew, a couple of the tables are overturned, not to mention the food spilled everywhere. They even ended up hitting more than one bystander in the midst of their fight.

The door swings open and Meliodas walks back into the Boar Hat. The two men, and everyone else in the tavern, freeze where they are. Meliodas looks around at the mess, and his mouth drops open.

"What happened in here?"

"Eek!" Hawk jumps, "Meliodas—"

"Just calm down Captain, it's okay. They'll clean up the mess they made." King floated over and took Meliodas by the shoulder, but he shook off King's hand.

"We-we're so s-sorry! Please forgive us!" The two men cry, dropping down to the ground. Meliodas looks down and everyone tenses up, bracing themselves for what may come next. But instead of wrath, it is laughter. Meliodas smiles widely and laughs, just like a little kid would.

"There was bar fight and I missed it!" Meliodas offers the men his hand and helps them stand up, still laughing.

Everyone looks shocked. I suppose they didn't expect him to be so collected with his emotions, which I rather odd since he must be the most relaxed person I have ever met. To their surprise, Meliodas isn't mad at all. He holds no anger at all, the only thing he does hold is cheerfulness and laughter. I smile.

"B-but what about the mess we made?" The two men ask cautiously.

"Oh, that?" Meliodas looks around and waves it off with his hand, "We'll clean it up later. Life happens, right?"

"Oh...r-right!" Then they are laughing too.

Everyone goes back to the way they were before, and the townspeople seem to relax a little bit more around the Sins. I guess it just takes time to get used to new people. And the fight the two men had earlier seemed to clear the air.

Later that night, when things have calmed down, we all end up going outside to lie in the grass. People are scattered around on blankets or just on open ground. The fresh smell of cool air surrounds us, and I can't think of anything that would make me happier than being with all of them.

I take a deep breath in, trying to savor the moment. I sit down next Meliodas who now lies next to me, his hands behind his head. The others join us too. With the sun fast asleep, and the moon watching over the dark sky, we look up at the starry night.

"Look!" King shouts, pointing.

"It's a shooting star," Diane says, "It's so pretty!"

"It's quite beautiful isn't it?" Gowther points out to Merlin. She just smiles in return.

"Make a wish," Meliodas says to me.

I feel so small under the big starry sky, but I guess I really am small compared to it. In this moment, I can't think of anything that I want. There is nothing to wish for. Everything about my life right now is absolutely perfect. Its perfect in every way possible, and I never want it to change. If I never got up from this spot, or if this were the last thing that I ever remembered, the last time I was ever happy, that would be okay. I close my eyes and tilt my head toward the shooting star.

I wish that we could stay like this forever.
