Starco Story. First time writing. Star and Marco's relationship must adapt and change as they come to terms with their own feelings as well as deal with troubling times in the Kingdom of Mewni.

This story explores my take on what happened to Marco during the 16 years he was gone and the aftermath that ensued. It will feature heavy Marcapoo and one sided Jarco and Starco with a progressive-ish StarTom. this story will be very dark and heavy and may end up including lemons later on. You have been warned.

Love is a complicated force, binding souls together across various strings. But the red string of fate is the strongest. No matter how you weave it, the attached pair will find their way together. Star and Marco learn to face the truth, restoring color to there lives. But challenges await them as they discover a deeper bond growing.

Follow up to 'My Dinner with Buff Frog'. Post 'Monster Bash'. Marco's feelings are tearing him apart, and now more than ever... He needs his friends.

Unable to take the heartache, Marco leaves Star and ends up getting some new abilities. Upon learning that Star, and even Mewni, could die without his help, he swears to defend her to the best of his ability. It's all on Marco, Star, and co. to save Mewni, Earth, and every other dimension, while working out their own personal issues. Rated M for lemons. Yes. Those things.

This is a story mostly about Pacifica Northwest and Dipper Pines, with just a smidgen of a shooting star and a floating triangle. Planning on the next big thing, sorry for being gone for so long, but I'm somewhat back, stay tuned for the next phase. Please feel free to leave a review
