Five years later
"Trick or treat" the small blonde kid said, big green eyes and dimples on full display.
Even though Harry kept saying their small boy looked like Louis, everyone couldn't help but think otherwise. He looked exactly like the triplets, and Edward was very proud of it. He was a mix of them all, and the child looked purely beautiful.
"Atlas, don't eat too many sweets." Louis told his son, poking his little cheek, he was so cute.
They'd decided to call him Atlas, Marcel had mentioned it during an argument and it made Louis shut up, the omega immediately fell in love with the name. Atlas Styles.
It was Halloween today, and the small child was so excited for it. Edward had promised him he'd go trick or treating with him, and he still wasn't home. Louis was sure he was hiding from his family, so he wouldn't have to go trick or treating. He's always hated halloween anyway.
"But dah', daddy Edward said-"
"What daddy Edward says is all stupid, okay?" Harry said, chuckling and picking his five year old son up.
Even though Atlas had blonde, curly hair and had big green eyes, dimples and the triplet's manners; he was very small, just like Louis. It made the three alphas melt. He had small feet, small hands, small fingers, everything was tiny.
"Papa!" Atlas yelled and hugged his father tightly. He loved his papa a lot and he was pretty sure the feeling was mutual.
At five years old, Atlas was quite the smart one, he could read a little bit, and he was very cheerful.
He tried to look as handsome as his brother, Jackson.
When the thirteen years old boy put cream on his face, Atlas did too, and whenever they were shopping, the small child tried to find the same things as his brother, and even though it annoyed Jackson, he really didn't want to upset the cute child that was his brother.
"Hello sunshine," said Harry, kissing his little boy's round cheek. "Happy to see you as well!"
Atlas grinned and wriggled in his papa's big arms.
"Put me down 'pa!" he told his father, looking over at Louis.
They all had a nickname, Harry was papa, Edward was daddy Edward, Marcel was daddy, and Louis was sometimes dada, sometimes mummy, and he really didn't mind that. As long as the nickname was cute and lovely, he definitely wasn't going to complain.
When Harry put the small blondie down, he looked at Louis with bright green eyes and asked :
"Please can i go outside play with Jimmy?"
And Louis knows this look, he knows these green eyes and he also damn well knows he can't resist them.
"Only until daddy Edward comes back!" he said, whining. And Louis couldn't help but nod.
At the end of his pregnancy, Louis lost a lot of blood, his life was in danger, and he got so scared for his life's and his son's that he promised himself that he'd never get pregnant again.
He already had two sons and the omega was pretty proud of it, and even though Edward kept begging him for a second child, Louis said no. He was too scared. So once the kid was outside, Harry brought up the subject for the third time of the week.
"You look so good.." Harry said, wraping his arms around Louis from behind. The omega was standing in front of the window, watching his small son run over to his neighbour's house. He looked so small and vulnerable outside, it killed him.
"Mhm.." Louis said, letting Harry kiss his neck as gently as he could.
"You'd still look better with a small tummy.." Harry said, still kissing Louis' neck, and the short man sighed and pushed Harry off him.
"I knew it." Louis said, already walking away with his ass swaying from left to right. He always managed to blow his lovers' mind, without even doing it on purpose.
In five years, nothing had changed. They were still in love. And you could ask anyone in town, every single person knew who they were. They were the Styles family.
Louis' life was perfect, and he never thought he'd end up being as happy as he is right now. He has two sons, three mates, a house and a dog. He was finally settled, and even after everything that's happened, he was sure of one thing :
They were his, and he was Theirs.
The End.
