Star Butterfly sprawled out on her bed and sighed. It was 4pm on a Saturday. She should be out having fun with her best bestie, Marco Diaz. That's how Saturdays should be spent, hanging out with the people you care about most.

Unfortunately for Star, that's precisely what Marco was doing.

It had been a few months since the boy had mustered up the courage to ask Jackie out on a date, and Star, being the amazing best friend she was, was incredibly supportive during the couple's first few weeks. However, as time wore on, and Marco and Jackie began going steady, Star slowly began to feel like she was being left behind.

Forgotten by her best friend.

That hurt more than anything she could possibly imagine. And she has a very active imagination.

So here she was, the bubbly princess of Mewni, laying on her bed, staring at the ceiling, while Marco was busy hanging out with Jackie. It's not like she wasn't happy for him. In fact, she was overjoyed to see Marco so happy. But she did feel left out.

On top of that, Star was beginning to ask herself some very difficult questions. Especially after the Truth or Punishment incident.

Though she didn't want to admit it, or perhaps she simply couldn't admit it at the time, Star knew she had been the one who lied. Deep down in her heart, she knew it. Though her brain told her otherwise, she was well aware that her feelings towards Marco were growing, changing. But if she allowed herself to accept it, she feared that she might ruin her relationship with Marco.

Her only option was to repress those feelings, shove them as far down inside herself as she could. But seeing the way Marco smiled at Jackie, the affection and love in his eyes as he looked at her, was constant agony. Star had considered coming clean. Perhaps it would be best if she simply told Marco how she felt. But then again, that could complicate things. It might make things awkward between them. It might drive Marco away.

So she continued to suffer in silence, as she slowly drifted farther and farther away from the person she cared about more than anything else in the universe.

Until, suddenly, a thought came to Star's mind. Another option. An option that, while it may only cause Star more pain, would probably be the best choice for everyone.

Star sat up in bed and glanced at the clock. It was already 8pm. A moment later, Star heard the front door open. She stood up, got off the bed, and slowly made her way to the staircase to greet Marco. She stopped halfway down the stairs and just stared at him. Marco had his back to her as he took his shoes off, but he soon turned around to see the young blonde looking at him.

He smiled at her. "Hey, Star. How was your—"

"I'm leaving."

A short first chapter, but more is on the way! Just as soon as I find the time to write it.
