Fandom: Adventure Time.

Ship: Fern x Finn/Finncest.

Warnings: Teenage related content, hardcore scenes and sensitive themes will be showed in this fanfic.

Note: This is not a fanfic like any other I've tried to write for "Adventure Time" fandom in the last few years, besides the fact that I've been postponing updates for a long time, I had the ideas, that I didn't lack, but the problem is that I didn't know how to assemble what I already thought of to create something that would get the readers' attention. So, now, after a long time thinking and postponing the writing of this fanfic, I think I finally found my inspiration to continue.

I was planning to adapt the story into a comic, but I think it will take me more time than I thought, plus it's hard for me to find my own style for the characters so I don't copy from other fan artists and end up being accused of plagiarism.

The fanfic may be subject to slight modifications as the plot progresses, besides I was inspired by another fanfic called "Confidencias de Papel" written by ELIARTT for LUCA film fandom, I don't know if I recommend it, with the little I saw I was filled with anguish, rage, I thought a lot about what happened to Luca and Giulia, as well as Alberto and other characters, and that didn't let me sleep at night. Maybe this fanfic will have references to what happens there, but I can't promise anything.

I hope you like it, to make this fanfic I based it on an Alternate Universe (AU) completely different from the original series and that I invented in my head looking at some fanarts I found on Tumblr... and... I may have been inspired a little bit by the first season of the British series "SKINS" so there will be references to that series, some books and movies I've read and seen before.

Adventure Time doesn't belong to me but to Pendleton Ward who is also "Bravest Warriors" creator (actually there are more seasons but I can't watch them because the platform where they are published is not available in my country) but the fanfic and its Alternate Universe (AU) are MY property.

Chapter 1: Finn.

The morning comes to the city and with it the night went away to give an appearance to the sun, a boy no more than sixteen or seventeen years old slept in his bed in his room. He could asleep a bit longer but the alarm clock on his phone began to ring what made him wake up, get up from his bed to pick up his phone to unlock it and turn off his alarm clock which he programmed to wake up in time to go to the school.

Look at the stars

Look how they shine for you...

He picked up his phone he had left on the nightstand, unlocked it, turned off the alarm clock, and saw the time 7:00 a.m. he still had a few minutes to go to the bathroom to brush his teeth, have breakfast, and then go to school.

"Oh, no...I don't want to go to school today..." the boy thought, throwing himself back on the bed, his eyes still narrowed with exhaustion.

Hey! This is me...Finn. Well, my full name is Finn Mertens...I'm sixteen years old, I go to school like everyone else and I live with my mom.

After getting ready to go to school, Finn came out of his room with the backpack loaded on his shoulder with the materials he needed for that day and started down the stairs to go to the kitchen to have breakfast. As she approached, her mother was in the kitchen putting the breakfast items on the table, she was ready to go to work, looked at the time on the wall clock and it was strange that her son still did not come.

"Finn, are you awake yet? Breakfast is ready" she asked and Finn suddenly made his appearance at the kitchen door.

"Yes, I am here, Mom" the boy replied, approached to his mother and greeted her with a hug as he sometimes did in the morning before he went to school.

She's my mom... her name is Minerva. So... you're asking yourselves "Where's my dad?" Um, it's sad for me to tell you, but my dad is dead, he tried to protect us from thieves who came into our house. My mom says I cannot remember that because I was only three years old when that happened.

There are no pictures of my dad at home, only one with him when I was little kid… sometimes... I would like to know more about him but my mom does not want to talk about it.

Finn had already finished breakfast, left his house and stood for a few seconds in the doorway with his hand resting on the railing of the small staircase leading to the door of the house where he now lived with his mother, his eyes they stared at the white clouds barely covering the sky, took a deep breath and started down the stairs.

After breakfast I go to school by but... but... today is a nice day so... I prefer to walk to school...

Not far away from Finn's house on a uninhabited ground, an almost orange-yellow dog slept in a hole he had made in the ground with some grass sprouting around him. He woke up when he hear a whistle from his friend, get up and rose shaking the dust of his fur and began to run out of the field to meet Finn.

"Good morning, Jake. I can't play with you now, I just come here to say you hi" Finn said as soon as he saw the yellow dog jump over him, waiting for the boy to play with him as he used to do every day. Jake looked at him and his eyes glittered with sadness when he heard that his friend would not play with him that morning "I'm sorry, but I have to go to school...I have an idea..."he dropped the dog and rose from the ground "let's play a race do you agree?"

Jake only barked as an answer, luckily his friend would play with him as he was on his way to school.

"Well, let's go"

The two began to run the way Finn walked in the mornings when he went to school, Finn could run fast but not as much as Jake, the yellow dog was taking the lead. After a few minutes running, Jake came first and Finn stopped, resting his hands on his knees to rest for a moment and catch his breath.

"You beat me, old man...I'm exhausted..." Finn said when his breathing became normal, he knelt in front of the dog "well, I have to go to school...then...I promise I'll play with you later"

While Finn was talking to Jake, a girl with long hair in a ponytail was standing outside the building watching the scene; another girl (who was probably her friend) walked towards her and stopped when she saw her with an expression of weirdness in her face.

"Hey, did you see that boy?" She asked, trying to get her friend's attention.

"Yes, I see him..." she said without looking at her, she only saw Finn and that yellow dog walk away from him until he lost sight of it "he was talking with a dog"

"Ha, ha, yes! Can you believe that? It's very strange...he doesn't have real friends"

"His only friend is that dog!"

Finn got up to hear what the girls said, felt a little embarrassed, so he quickly entered the building to keep from listening to them.

In all my life I never cared what the people say about me... but those girls really hurt me...

Upon entering school, Finn went to the first class of the day; today was Monday therefore the first two hours had Chemistry classes. It could not be said that the boy excelled in the subject, because he was not very good in Chemistry and much less in maths but he made an effort to pay attention in class, sometimes...

"Well, class...today we are going to learn about the atoms" said Professor Bonnibel, who was the one who imparted that subject, pointing to the blackboard where she had written the name of the lesson they would have that day "Can anyone give me a definition please?"

"An atom is a small amount of substances that if you fuse them...um...they become an atom" said one of the boys in the class.

"No, Mark. That's not the right definition. Can anyone give me another definition? "Bonnie asked, looking at the boys and girls in the living room, most of them chatting with each other or get busy on other things, her eyes fixed on Finn "Finn!"

"Hey? What?" Finn said, coming out of his trance, apparently not paying attention and staring at the window "um...I...I'm sorry, Professor. I was not listening, could you repeat the question please?"

"Focus, Finn. It's the fifth time I've caught your attention in my class" Bonnie said, a little frustrated that she had to deal with him every time she distracted herself during a lesson. She looked at her students again "I know that you find it "boring" to be here but if you strive and focus you will be able to see the entertaining side to this lesson...now who else wants to give me a clear definition of what an atom is?"

The hours of chemistry class along with those of other classes passed quickly, at 12:00 the bell rang announcing that it was time to go to lunch. The boys put away their things and went out into the dining room. Finn was not in such a hurry to go to lunch because after all, no one was expecting him, he could go a few minutes later and then he would have time to get to the last lesson of the day. He started to save things and while the two girls who had been talking about him that morning when he came with Jake to school walked towards the exit as they talked between them and laughed but when they saw the blonde stopped laughing.

"Hey Finn!" The girl with her hair pulled up in a ponytail trying to be nice to him "hey, listen... If you heard us talk about you and your dog, um...my friend and I wanted to apologize"

"Yes, you should not have taken that conversation seriously. It really gives us a little envy that you have a dog as a friend, if I could have one I would be his friend too" said the other girl also wanting to pretend she was sorry for what she said that morning.

"It was not necessary to come and tell me that you are sorry for what you said" Finn said, finishing his belongings, got up and loaded his backpack, "because I see that you are not sorry, besides...Jake is not my dog, he is a dog that lives in the street and still consider it my best friend"

I don't know when I started to see Jake as my best friend, I take care of him since I have memory... when I found him he was inside a trash bag, hurt and mistreated, I never knew how it ended up like that. Sometimes I think my dad sent Jake to take care of me and I feel I can see him through his eyes, although that is impossible.

The two girls looked at each other, unable to believe what they were hearing and left without saying anything else. Finn rolled his eyes and left the classroom to go to the cafeteria to eat something before the next (and last) class of the day. When he arrived at the cafeteria he took a sandwich and a soda and went to sit as far as he could, the last time he sat alone near the door bullies were bothering him a long time until he left, he hoped that situation would it was not repeated again today but he was wrong.

He barely sat down when he heard footsteps approaching the place where he was sitting, looked up and saw a group of four boys standing in front of him.

"What?" Finn said, none of the boys answered "What do they look at me?" If you want to sit, I'm sorry but ...this place is busy"

"Good afternoon, Freak" one of the boys said with a certain sarcasm "are you not going to say "hi" to us?"

"No, I do not have any interest in doing it anymore ... and if you'll excuse me, I want peace of mind, thank you very much," Finn said, taking his sandwich and soda ready to leave the cafeteria, but another of the boys stopped him, sit in place.

"Oh, I'm so sorry...I didn't know that freaks need peace" exclaimed the boy, taking Finn by the shoulder, he saw the soda can and took it without giving Finn time to stop him.

"Wait, what are you going to do? That's my soda"

"Listen, you...you want quiet, don't ya?" The boy asked, Finn said nothing and just nodded "I'll give you your quiet!"

Then the boy threw the soda wetting the hat, the face and part of Finn's clothes. The blonde stood still without saying anything, without moving, for a second he wanted to get up and want to defend himself from what that boy had done to him but could not do it, something was preventing him and could not find out what it was, he heard the can of soda falling to the floor. With the sound of aluminum cam falling to the ground everyone turned to see what had happened, now Finn was more embarrassed than usual and more with the other students seeing the situation.

"I think it slipped from my hands" said the boy with his hands up, burst out laughing, struck the table with both hands frightening Finn and came dangerously close to him-get out, I do not want to see you around Did you hear me, phenomenon?

Finn looked at the boy, and then saw the other students who looked at him without understanding what had actually happened and waited for him to say something and then he got up, took his bag and ran out of there. Once outside the cafeteria, he started down the stairs that would take him to the first floor, ran down the hall until he reached the exit, opened the door and left the school, but when he left he looked both sides of the street and he stood there for a few minutes without knowing what to do.

I was lost, I didn't know what to do as soon as I left school... I had nowhere to go and besides I could not go home for another two hours and if I returned I would be alone, mom would not leave work until later...

At the end he turned right and started running away from school, he needed to go somewhere else, to be alone with his thoughts without anyone bothering him and also needed to calm down but it seems that today the destiny was against him because he ran into someone causing it to fall to the ground and hurt.

"Agh..."

"Hell! What's wrong with you? Look where you walk, you almost broke my guitar" said the person with whom he collided, Finn began to stand up without looking that person in the eye.

"I'm sorry, I didn't want to do it..." the boy apologized, finished getting up, walked to the person with whom he collided and looked up "my name is Finn, who are you?"

"I am not interested to know your name, and you don't want to know mine either, so I will not tell you" The mysterious person adjusted his green and white guitar behind his back and brushed the dust off his black jacket, but he barely saw the boy he had hit he could see he was sad "hey, what's the matter? Did you like what I said? Please, it was not too bad..."

"It's not because of that! I don't want to talk to you, I hardly know you...you know what? Leave me alone" Finn started to walk away from the boy, pushing him slightly, he just watched him walk away, shook his head to get out of his little trance and left.
