You lost your father in the war against the monsters. If it was up to you every last being that fought against man would be sent to execution. But it wasn't your choice.... unless it was? That's when you decide to visit the underground. All you needed was one excuse to rage another war against the monsters this time without showing mercy. But what you didn't expect was HIM. The monster that gave made you question your own methods. The monster that didn't treat you like a freak. The monster that gave you the only aspect you lacked.... HOPE.

!!!DISCONTINUED!!!(Before we get into what this story is about, I would like to clarify a few things. this story may contain some Hamilton references. It won't have any smut because I get awkward at those parts. The most that will happen is kissing. If you want me to make a smut chapter, comment. My notes during the story are at the beginning, and end of the pages and sometimes in parenthesis and bold. I will try to correct my spelling as much as I can. I will try to make this gender neutral. The art does not belong to me. If this is your art and you don't want it on here, dm me on instagram @toadmarioandluigi. When I say Second Person, I mean when I say the pronoun you. I will not be updating frequently since school.) Key (if more come up I will reupload key in the same chapter) Y/N = your name N/N = nickname H/C = hair color H/L = hair length S/C = skin color P/N = partner's name (if you don't have one, make up a name) B/N = brother's name On to the ACTUAL description of the story (surprising, I know) You have lived in the forest for most of your life trying to survive. The forest you lived in was in between Mt. Ebott and a little town. (can't think of a town name) You would watch the town and see how they act. After a few years, when you were grown, a war started between monsters and humans. It happened in the forest you had live in for years. What will you do? (Not like you have the choice, I'm the writer here but whatever)
