A Star vs the Forces of Evil fanfic alternate universe where Star grew up on Earth but has reminiscing memories of her life on Mewni. (Yes, she is living with the Diaz family).

"Well, it is what's best for her."
"Indeed."
"So, I guess it must be done."
"Quite so."
The two royals gazed at the sleeping child in the mother's arms. She vowed not to show any emotion during this, but it was a bit difficult. After all, it's never easy proctecting the ones you love, is it?
"Good-bye dear. I'll see you again soon, I promise."
The baby smiled in her sleep. They gave her to the kind woman in front of them, her husband behind her. They looked at the girl joyfully.
"Marco will be delighted to have a friend. Thank you. I can assure you she will be taken care of."
The two royals nodded curtly and stepped through a portal, transporting them home. The two remaining parents looked at each other lovingly and then at the girl. She was going to feel right at home.

"Hey there Marco! Look! We brought you a friend! Mrs. Diaz told her son, although she doubted he knew what she was saying. Hey was barely a year old, but he was very bright. Mrs. Diaz set the girl down next to her son in the crib. As she did so, the little blonde's eyes began to open. The boy watched her, intrigued by this new person. She smiled, opening her eyes and looking at the people around her. As far as she was concerned, they were her family.

"Staw! Staw! Where awe you Staw?"
The little boy crawled around, trying to find his best friend. Only 3 years old, and already they had a special bond. He was giving up hope, when he heard a familiar giggle coming from the kitchen.
"Mawco! Wook! Cookies!"
The little blonde smiled, holding up a chocolate cookie for the boy to see. His eyes gleamed with happiness, as he took one from his friend. The two toddlers giggled, eating cookies and playing games.

"They look so peaceful." Mrs. Diaz said softly to her husband as she draped a blanket over a sleeping Star and Marco. Her husband smiled back at her.

"They do. I'm glad we were chosen."
His wife nodded. "Do you think she'll ever find out?"
"She has to, eventually."
Both parents looked down at the sleeping children, their hands intertwined and covered in cookie crumbs and chocolate chips.

"Not St. Olga's Reformatory School for Wayward Princesses! Please! Anything but that!"
"I'm afraid it's settled Star."
"No, you can't do this to me! I'll change, I promise!"
"That's what you've been saying. I'm afraid this was your last chance. It's time for you to go."
"NO!"
The blonde-haired girl shot up in her bed, screaming at the top of her lungs. She knew she shouldn't, but she had a nightmare. She couldn't explain why, but it all felt so...real.
"Star? Are you in there? Are you okay?" Someone asked from behind her door. She smiled and let out a small sigh of relief. "Y-yeah. Just fine." She said, unconvincingly. The boy from behind her door came in to find a distraught Star sitting on her bed, her head on her knees. He sat down on the bed with her.

"Hey Star, what happened?"
"It was nothing."
"So you just decided to scream in the middle of the night?"
"No. Wait, did I wake up your parents?"
"No, they can sleep through almost anything."
"Okay, that's good. I wouldn't want to worry them." She mumbled.
"Star, I'm worried. What happened?" He placed a small hand on her knee.
"I had a nightmare." She whispered, almost inaudibly.

The blonde felt weak and helpless, as tears pooled in her eyes. Suddenly, she felt a pair of arms hug her awkwardly. She accepted the hug, embracing him.

"Thanks Marco."
"Anything for you Star."
"Um, Marco?"
"Yes?'
"C-can you, um, stay with me?"
"Of course."

Marco let go of Star and climbed under the covers next to her. She snuggled up against his warm frame, as he wrapped his arms around her.

"Thank you Marco. For everything." She mumbled, drifting off to sleep again. "Anything for you Star. Anything."
