A/N: This is my first time writing elsanna. Even though it's set in a Modern AU and they aren't sisters, it's my first contribution to this fandom. I wrote it the past week following the prompts for the elsanna week in tumblr. I'm publishing this and the next chapters just as I published them in my tumblr. I'm planning to expand this story and continue it beyond what I already covered, but that will be published apart.

Day 1: Love at first sight

The first day of school. She was the new transfer student at this freaking elitist private school, and she was getting late. Anna never was a morning person, and with of all the hustle of moving to a new city, she was tired, actually, she was exhausted. Why on earth her grandfather, who she had never seen in her entire life, suddenly wanted the best for her and her mom? Maybe it was his way to make up for fifteen years of having banned her daughter from the family, but at least he could have the kindness of getting them a car to go to that damned distant school.

Mom had to work, so she woke up early and left. Because working at her father's company was a hell lot of pressure and the pressure was even worse if she was planning to reconnect with her strict father who had kicked your ass out of the family so many years ago. Anna could understand all the issues her mother was going through. Sometimes she felt guilty for her mother's family situation. If she wouldn't be born, probably nothing had happened. Anyway, all those worries didn't change the fact she was getting late to school on her first day.

She had to take the bus which left her in the middle of nowhere and then using her phone's GPS she localized the school which was uphill. Who was insane enough to build a school on a hill? So, she ran as fast as she could; her uniform was tight and uncomfortable. She took her shirt out of her skirt, otherwise, she would wind up suffocated.

Finally, she reached the huge and imposing gates of the building. Thankfully they were still opened. She looked around and let out a whistle at her amazement. The place looked as a castle from a fairy tale; a welcoming yard extended before her eyes. It bloomed with the green from the trees and the colourful mixture of flowers. The green was interrupted by the blue navy sea of girls in uniform who were leading their march to the main building.

Anna was so lost in the sight she had before that she hadn't entered yet. The ringing bell announcing the beginning of classes woke her up from her daydreaming. The doors started closing with an electronic buzz, and then Anna realized she was about to get out if she didn't hurry.

"Oh, no, no, wait!" she pleaded sliding just in time before the doors shut closed.

Once inside the yard, she kept running only focused on getting in time to her classroom which she had no idea where it was. She wasn't aware of the eyes from the surrounding girls set on her, and she didn't hear when someone yelled: "Beware!". It was too late. She had bumped into someone and then she was sprawled on the floor. Her uniform was a mess, her skirt barely covering her underwear, and the horde of girls around her whispering and watching her with a very disapproving look.

"Who is she?"

"She must be new."

"She ran into the president!"

"The Ice Queen is going to kill her."

Anna was on the verge of crying when she looked up and found a pair of blue eyes piercing her soul. For a moment, she thought she was in the presence of a fairy or a goddess. The girl in front of her didn't show any trace of emotion on her pale face that looked more like a sculpture. By the way, a beautiful one. Her blonde mane was tied into a braid that shimmered against the sun. Then, the girl's lips curved into what seemed to be a faint smile and a light pink tint covered her cheeks.

"Are you all right?"

"Who? Me?" Anna look around to see if there was someone else to whom this girl was talking to.

"Of course, you're the one on the floor." The girl smiled shyly, and with a swift movement, she hid her lips with her hand. The other girls around started laughing, but a single glare from her was enough to keep them silent. Then, she lent her hand to Anna to help her get up.

Anna blushed and hesitated for a moment. She took the girl's hand in hers and stood up.

"I'm Elsa. Elsa Frost."

"I'm Anna Summers."

"Welcome to Arendelle School, Anna."

They were still holding hands, and Anna was feeling something she had never felt before in her life. She didn't know how to call it, or if it even had a name. The way Elsa looked at her, her sweet voice, and the soft touch of her hand, all made her felt like she had butterflies fluttering in her stomach. It was love at first sight, but she couldn't know it because she had never been in love before.
