I will always be there for you, my little Snowflake

It has been a long day for the 15 year old Princess of Arendelle. She had to attend her parents' funeral without her sister Elsa. Desperate to at least get her sister to open her door for once she walks down the halls to her sister's door.

The door that has never been opened to her for years.

Instead of her usual special five knocks on her sister's door it was only a normal knock. No response. Anna began to softly sing to Elsa's door.

Elsa?

Please, I know you're in there

People are asking where you've been

They say have courage and I'm trying to

I'm right out here for you

Just let me in...

Elsa heard her sister through her closed door. I'm so sorry, Anna... She thought to herself as Anna continued.

We only have each other

It's just you and me

What're we gonna do?

Do you wanna build a snowman?

Elsa couldn't take it anymore. The years of solitude immediately took their toll on the Crown Princess. She opened her door. For the first time in forever. She picked her sister up off the ground, swiftly giving her precious Anna a hug before dragging her in. The embrace continued for quite sometime now.

The eldest sister peppered a few kisses on the youngest sister's cheeks. It's been so long since she got to touch and show affection to her baby sister. At the times of need for her, Elsa wouldn't even be there to give her comfort. Anna needed her sister. She's now only family she has left, she's the only blood relative.

After stopping they gazed at each other lovingly. Anna was the very first to speak, "I missed you so much Elsa..." Her sister's response was a tight embrace. "I missed you too Anna..."

"Elsa?" The youngest sister tentatively whispered.

"Hmm, what is it?" Elsa murmured as she slowly played with Anna's braids.

"Can I ask you something?"

"Name it, Anna."

"Stay with me? I don't wanna lose you."

Elsa's eyes were glossy with tears threatening to fall and so were Anna's. She pulled Anna closer to her and whispered in her ear, "I will stay with you. Can I ask you something also?" She felt Anna nod against her chest. "Do you wanna build a snowman?"

Anna gasped before murmuring. "I do... But how? It's spring."

The Crown Princess smirked, "Is it?" Elsa thought everything through. She conjured up a winter wonderland for her and her sister. Anna didn't question her. She was only jovial that she has her sister back. Before they started rolling the snow for their snowman Anna pulled her sister into a hug.

"Elsa?"

"Yes, Anna?"

"Will you always be there for me from now on?"

"I will always be there for you, my little Snowflake."
