Long ago monsters and humans lived in peace. Then one day a war broke out between monsters and humans. The humans were victorious and by the sacrifice of seven brave human souls. They sealed the monsters underground but two monsters were still on the surface. Wolf monsters one the eldest was named Mina the other the youngest was Rosaline. Years have passed and Mina the eldest met a man. He had chocolate brown hair and sapphire eyes. She talked to him and they got along.
As days became weeks Rosaline saw her sister Mina and Eric as they learned his name for he trusted them. We’re starting to become close. She smiled for her sister. As weeks became months and months became year’s mina and Eric had a family, twins for their first child. A little boy named Zero a monster like his mother and a little girl named Kaitlyn a human. Their next child is a little girl half monster half human. She had a twin sister but died in the birth. It has been four years since the human monster hybrid was born. Her name is Heart. She has white hair and red bangs her wolf tail and ears are white too. 
Her bangs cover her right eye to hide it as her right eye is a red like her mothers and her left eye is a dark blue like her fathers. She has never made friends but she doesn’t care. She lives with her aunt and siblings. She never met her parents for they left her and her siblings with their aunt when she was three months old.she was still happy she still had a family that loved her. But this is where it all begins.
“I don’t understand, am I really that different?” Heart asks, she is ten years old and lives, in the underground with her adopted family. Her white hair grew with her bangs, tail and ears her hair is in a braid but her bangs are in the same place her red eye gone. Darker to almost a blood red but her blue eye stayed the same. She's wearing a light blue jacket with fur around the hood, long blue jeans, a red beanie and snow boots. A white and light blue backpack lays beside her while she lays against a tree near snowdin. A black wolf is floating behind her left shoulder almost translucent his eyes are red with a black pupil his fur dark as night that is his name Night. On the other side is a human girl with brown hair, blue eyes, peach skin, wearing a red shirt with black jeans and sneakers. She is floating and almost translucent too.     “it's not that you're different, you're just…. Um…. Special” the girl said on the right her name is Lily Heart looked at her and smiled. “Lily is right Heart you are special” night said Heart was very happy the two spirits were her only friends besides a human named Chara.
The heart's soul is half red half white the white sideshows Night the red sideshows Lily. Heart gets up, grabs her bag and teleports back to the royal castle where she lives. She walked in and saw a goat woman monster named Toriel Dreemurr “my child, where have you been I was very worried about you” Toriel said as she walked to heart and picked her up. Heart hugs Toriel and smiles “im sorry mom I was near snowdin I just needed some time alone that was all” Heart answered Toriel's question. toriel smiled and kissed Heart's forehead "okay my child, but don't scare us like that again" Toriel told Heart. she carried Heart to the lab, she opened the door and set Heart down. "HEART!” Heart looked and a little skeleton jumped into her arms hugging her. Heart giggles and hugs back, the skeleton has a red scarf on that's a little too long for him, a orange coat with pants to match and red boots.
Heart put the small skeleton down and saw another two skeletons one was the tallest. He had on black pants and black dress shoes’ a greyish black sweater on and a white lab coat. The smaller one had shorts’ sneakers and a hoodie similar to Heart”s “ah, Queen Toriel, i'm surprised to see you” the taller skeleton said but stopped when he saw Heart with the Queen. “ dr. gaster, please keep a betet eye socket on Heart” Toriel told him.
Heart was with the other two skeletons ''hi Sans, i'm sorry i left i just needed some time alone” Heart apologized to Sans with the blue hoodie. “Its okay, i know how you are besides you just need some HUMERUS in your life” Sans jokes ''SANS” the little skeleton yelled at his older brother Heart started to laugh “what, come on papyrus im just being SANS - ational”Sans said Papyrus just got madder at him. Heart kept on laughing sans laughed with her. "he is very funny isn't he?" Lilly said heart looked at her and smiled "of course he is always funny" heart replied Sans and Papyrus looked at her. "Heart?who are you talking to?" Sans asked Heart looked at him and smiled "i forgot, you cant see her I'm just talking to Lilly that's all" she said. She always thought of Sans and Papyrus as brothers but Dr. Gaster was more like an uncle to her. The door opened again she looked and saw her big brothers. "Chara! Azzy!" She yelled running to her brothers giving them a hug Asriel smiled and hugged back.
Chara hugged back as well with a big smile "hi Heart, we came to see how you are doing with Dr. Gaster, is he paying attention to you?" Asriel asked. He has his signature yellow and green striped shirt on with his brown caprese pants on. Chara wore the same thing, Chara used to have hi brown hair over his eyes but after a while he had their mom cut his bangs for him. He is now comfortable showing his eyes now. His eyes are a red color but it's a lighter red then Heart's.
She smiled and nodded her head over time they all talked and joked around Papyrus getting mad at Sans jokes and puns. Chara rolling his eyes at the puns and jokes while Heart and Asriel just laughed at them and made Puns with him. As night time rolled in the five of them are passed out asleep Heart laying on Chara holding Papyrus close Sans next to her also holding Papyrus. Asriel is on the other side of Chara asleep holding Heart's hand. Gaster saw this and smiled he knew that he wouldn't be able to get his sons back from Heart for she is very protective of them, she growled once in her sleep the last time he tried to get Papyrus from her. She nearly bit him. So he used his magic to levitate them and brought them to Heart's room. She has two beds in her room a small one for herself and a larger one for when she sleeps with one of her siblings when she has a nightmare.
He lays them on the larger bed and took their shoes off. He takes their jackets off and tucks them in. He grabs a stuffed white fox from Heart's other bed and hands it to her she hugs it with Papyrus. He smiles and turns her nightlight on he walks to the door looks at the kids one last time and closes the door. He sees the king, "ah, king Asgore, you don't need to find the children they are in Heart's room sleeping" he tells the king "well that's good I'm worried about Heart though," he said. Gaster gives him a confused look and asks why.
"Well, she seems to talk to herself and responds to herself as well, I know children her age have imaginary friends, but, when Asriel asked her who she's talking to she says it's her other sides of herself. Do you think you could see what she means by that?" He asks Gaster. Gaster understands for he has seen her do that before and she has done it earlier before in his lab " alright I will see what I can do, I'll ask her some questions and maybe run a test on her soul for how unique it is for she is the first human to have a half of a monsters soul" he said they talked for a bit longer and said their good byes.
Gaster walks back to his lab and starts working on the test he needs for Heart when she wakes up. "I hope she will let me do this to her, I don't want to lose her trust, she is like the daughter I never had." He said he got back to work until he passed out at his desk.
