This is my first fanfiction that I have written. I hope you all enjoy it and if you have any advice or constructive criticism is welcomed to help this story and future stories grow. Star is a little OC in the beginning, but she will eventually return to the Star that we all know and love. Thanks Everyone!

Disclaimer: I don't own Star vs the Forces of Evil, I never have or will. If I did Starco would be official and Marco would be the definition of a Badass.

Agony

Why?

That one simple question is the only thing that is running through his mind. Over and over again, non-stop why why why why why why…. It just won't stop. What did he do to deserve this pain, this sadness, this hate?

Marco Diaz just turned 15 years old, and instead of having an amazing birthday where he is surrounded by his friends and family who love him… he just had his heart mercilessly ripped out by his so called best friend and secret crush, Star Butterfly. He had tried to take Kelly's advice that she had kindly given after their time spent watching the Soulrise.

"Marco, you need to be honest with Star about your feelings for her. If you aren't, then you will never know if there was a chance the two of you could've been together and you will carry that regret for the rest of your days." She said

Marco thanked Kelly for the advice and when he and Star returned to the castle, he asked if he could talk to her for a minute. He put all of the past behind him at this point, how she confessed her feelings and left him alone, confused, and embarrassed in front of all their classmates, how he had sacrificed his life on earth, his girlfriend, his parents and friends to be with her, how when he returned to Mewni he was greeted with a cold response from the royal family, despite how much he had saved and protected Star in the past, he even put the fact that she had admitted to liking him and then a few months later, she had moved on to her ex-boyfriend Tom and tried to make him stay in the sub-basement of the castle as a squire to the Knight of the Wash. He just wanted to forget the past and tell his best friend how much he loved her and appreciated her. The response he got, was not the one he thought he would receive.

*Smack*

She slapped him, and not a playful slap like he was used to or even an annoying (secretly endearing) slap like he got from Heckapoo no, this slap was delivered with the intent to harm. She then proceeded to tell Marco exactly what she thought, how much of a burden he had been since his return to Mewni, how much she wished he would've just stayed on Earth, how much better of a boyfriend Tom was compared to Marco, and the one that hurt the worst of all…. How much Star wanted for him to just disappear.

So Marco responded in the only way he could think of…. He took his dimensional scissors that he spent 16 years earning for Star, cut open a hole that led to a random unspecified dimension, and jumped through. Star, seeing this, shakes her head and walks off to her room. She believes that he depends too much on her, so it is only a matter of time before he returns. She doesn't know just how wrong she is.

Marco finds himself, laying on a beach with grey waters and an emerald green sky, heartbroken beyond belief. Then and there, Marco swears that no one will take advantage of his heart the same way again. He will show Star just how wrong she is, that it was her that depended too much on him. He'll show everyone, this he swears.

It's funny how simple words, could push someone into becoming who they truly are.
