Thor and Loki watched as their mother held an infant in her arms, a smile was painted on her face. Frigga saw confusion on her sons' faces, and she gave them a nod.

"Want to come and see your little sister?"

Thor and Loki were just children at that time, and they wondered when did their mother gave birth of a baby?

Thor was the first to walk towards his mother who was sitting in bed with the newborn--- you, in her arms. Thor put his hand on his little sister's tiny hand, a smile started to crack on his lips.

"Loki, look! She's adorable."

Thor's words influenced Loki and he quickly went to see you as well. His heart swelled in joy when you wrapped his fingers in your tiny hand.

"I think I already love her."

Loki said, making Frigga chuckled under her breath. As soon as her eyes landed on you, she knew you would be a lovable person. You were just a baby, but you already stole the princes' hearts when they met you.

"Mother, may I ask you something? Where did she come from?"

Frigga smiled at Thor's question. Her sons were smart. They knew that you were not from Asgard, you were different.

"She's a Midgardian. But now she's one of us. She's your little sister now."

Loki and Thor nodded at their mother's words. Midgardian or Asgardian--- They paid no attention to your heritage because whatever it was they would love you until the end of time.

...

"Where is Y/N?"

Loki asked Thor who was sparring with Lady Sif and Fandral. Thor's eyebrows furrowed as he pondered where his sister might be. When he realised that he did not see her all day, he shook his head at Loki.

"I'm sorry but I do not know, brother."

Thor responded, worry started to wrap around his heart when he did not know where you were. Loki sighed and he was going to nag at his brother when you came running into the room, crying your heart out.

"Y/N, what happened to you?"

Thor dropped every thing he was doing and walked towards you. He signalled his friends to leave and they did without any questions. Loki's heart broke into tiny little pieces when he heard you cry. He did not wait to pull you into his arms, engulfing you in his warmth and comfort that you needed.

"They--- They hate me."

You managed to say between your sobs. Loki tightened his arms around you whilst Thor was raging with anger when he realised that somebody was messing with his little sister.

"Y/N, you're an adorable person with a big heart. Who would say such thing to you?"

Thor asked softly, making you pull away from Loki to look at your older brother.

"But Thor, they said that I do not belong here. I just want to be their friends!"

You told your brother and he immediately knew that the children of Asgard were hating on you. Loki curled his hands in fists and he was going to leave and finish them off when Thor stopped him.

"Loki, don't."

"But they hurt our sister!"

"They're just kids, Loki."

Loki rolled his eyes at Thor's words but after seeing your face, his heart softened. He looked at you and he knew you would not want the children to be harm.

"My Y/N, please do not listen to their words. You're our sister, and you belong here."

Loki said, a smile was plastered on his face. As a little girl, you were comforted by his words and you nodded violently with a big smile on your face.

"I love you, brother!"

You kissed his cheek and he laughed at your cuteness. Thor pouted and he pretended to be hurt. You laughed when he put a hand on his chest dramatically.

"What about me, little princess?"

You went to give Thor a peck on his cheek as well as you did to Loki, making a smile grew on his face.

"I love you too!"

You said to Thor, giggling afterwards. Loki could not help but grin as he pinched your cheek.

"Thor, she definitely loves me more."

"In your dreams, Loki."

...

It was silent in the library and Loki found it rather peaceful than being in the crowds of people in the celebration that night. The God of Mischief left the celebration early and decided to sneak into the libary without telling anyone.

Loki was starting to get comfortable in his couch with a book in his hands when someone coughed, alerting him of their presence. Loki's eyes grew wide when he saw you walking towards him with a smirk on your face.

"My darling little sister, what are you doing here?"

He frowned. You laughed and sat next to him on the couch, taking his book out of his grasp and put it on the table.

"I was suffering in the celebration and I can't believe that you left without me."

You crossed your arms against your chest but you failed to hide your smile. Loki shrugged his shoulders and smirked at you.

"Suffering? I thought you were having fun with your new friends."

Loki said as a matter of a fact when he was in the celebration, he saw you talking and laughing with the guests who were your age. Those teenagers seemed to adore your charm and personalities.

"Well, I was. Until Thor decided to punch one of them in the face."

You muttered, only making Loki laughed at your words. You looked at your brother in disbelief.

"Thor did that?"

Loki kept laughing and it annoyed you. Loki knew Thor must had a reasonable reason to harm the guy who was with you.

"The only reason I punched him was because he started to touch you and you did not like it."

You and Loki noticed that Thor was in the library, a smile was on his face. Loki nodded at Thor's words and now he was aching to punch the guy as well.

"But brother, you can just talk to him, right?"

You flashed them an enchanting smile but that did not work as they were really protective of you. Thor took a seat beside you on the couch and you could not help but smile when you had your brothers with you.

"You're becoming a beautiful lady, Y/N. And you're a Princess of Asgard. As long as we are alive, we are entitled to protect you."

Thor said, nudging you with his elbow. You laid your head on Thor's lap, making he laughed. You put both of your legs on Loki's lap, a sigh escaped your lips as you were getting comfortable on the couch.

"This is so much better than being in the celebration."

You mumbled. Loki and Thor just smiled at your sleepy form. Your eyes were starting to shut and dreams were taking over you when suddenly---

"Well, here you are. I thought my children were missing."

You were very much awake when Odin's voice was heard in the room. You sat up and a guilty smile was painted on your face. Frigga was looking at three of you with a knowing smirk.

"Even if they have gone missing, they would still be together. Thus, we do not need to worry."

Frigga said to her husband who gave her a smile. You changed looks with Thor and Loki. Without any other word, your parents left the library. A relief breath escaped your throat. You and your brothers burst into a fit of laughter and all of you ended up sleeping in the library, and triggering the anger of your mother in the next morning when she found three of you, sleeping uncomfortably on the couch.

...

You had grown to be an exquisite lady with a trailblazing mind. You were a charismatic princess who your father was proud to tell to the world of. You were exposed to the royal duties more now, that you were an adult. The trust that your parents put on your shoulders was meaningful to you.

Although it was a little bit hard for you to stay smiling all day and acted like every thing was alright even when your mood changed here and there. You wondered how did your mother do it easily.

"Princess Y/N, it's hard to see you now. You are very busy, I suppose."

You chuckled at Thor's words and you ran into his arms, hugging him like your life depended on him. He hugged you back, kissing the crown of your head lovingly.

"I miss you very much, brother."

You whispered softly into his chest. You could feel his chest vibrated when he laughed. You glared daggers at him and punched his arm playfully.

"What's so funny?"

"Nothing. It's just.. My little sister is growing up so fast."

Sadness was laced in his voice, but he was a proud brother as well. He kissed your forehead and you chuckled under your breath.

"What do you have to do tomorrow?"

"A dancing lesson."

Thor raised his eyebrows at you and pondered for a moment. Then he took your hand and you both walked to Loki's chambers.

"What are we doing here, Thor?"

Loki was a person who rather not to be disturbed when he was already in his chambers, hence, you wondered why would you be here late at night.

"Loki is a great dance teacher, if you want to know."

"Oh, really?!"

Both of you and Thor were flabbergasted when the door of his chambers opened, revealing an irrirated Loki.

"Why aren't you asleep yet and why are you both in front of my chambers?"

Loki pressed his lips into a thin line and waited for your response. You looked at Thor who was grinning like a child.

"Perhaps you can teach Y/N a dance? You know, to make her life easier tomorrow during the lesson."

Thor said to his brother and Loki rolled his eyes in annoyance.

"When did I become a dancing teacher, Thor?"

"Well, you taught me a dance when I wanted to go out with my first lover."

Thor said, trying to win Loki's favor. You smiled broadly at the God of Mischief and finally, he let you and Thor in into his chambers.

"Yeay, thank you Loki!"

You embraced him and Loki chuckled at your doings. His heart melted since the first time he saw you, and now, his love for you was only getting stronger.

"Thor, are you just going to stand there or what?"

Loki asked, raising an eyebrow at the prince. You took Thor's arm and asked him to dance with you.

"Come on, it'll be fun!"

You giggled. Thor put his hands up and refused your offer.

"I'm an awful dancer, Y/N."

"Trust me, brother, I know."

Loki said, a smirk was dancing on his lips. Thor groaned when Loki was challenging him. The dancing lesson turned out to be so much fun because there was more laughing and fooling around rather than dancing but you loved it.

It was late at night and from exhaustion, you and your brothers laid on the floor, watching the night sky from the opened window. Thor kept making jokes and Loki gave his sassy remarks, making you laughed every time.

The laughter from Loki's chambers seemed to disturb the peace of the palace when a knock was heard, shutting the three of you up for good. The door was opened and you could see Frigga put her hands on her waist.

"I swear, three of you are children sometimes!"

She said, once she saw you lying on the floor. However, a smile was plastered on her face.

"We are your children."

You said, making your mother chuckled softly. Thor and Loki wrapped their arms around you and Frigga came in to kiss your forehead, before moving to kiss Thor's and Loki's forehead.

"Yes, all of you are going to be my beloved children forever."

She whispered, a soft smile decorated her face.

"Thor, please control your voice. I can hear you laughing from my chambers."

Thor gasped dramatically, he never thought his voice was that loud. His mother's chambers was far from Loki's, therefore his voice must be too loud for everyone's liking that night.

"I think we need to start a---"

Loki said, and he looked at you with a knowing smirk. You understood very well with what he intended to do but Thor was puzzled. Both of you and Loki looked at Thor and he frowned in confusion.

"What are you guys implying---"

"Tickle fight!"

You and Loki started to tickle Thor who was defenseless on the floor. He could not contain his laughter and soon it won't be Frigga who knock on the door, but it would be your father.

"Thor, stop laughing! Loki, you should not let your siblings into your room at this hour and Y/N, please stop tickling your brother!" 

Time passed and the seasons changed but it was always the same for you and your brothers. You caused problems together and your parents had to remind three of you to behave like you were supposed to.

Nevertheless, you would always be together. Forever.
