You were a demigod... Being in Human Child body... You were 13 years old, you weren't aging at all... But the thing that... After barrier broke and Monster-kind was free, Humans got along with Monsters pretty well... but... You always get strange looks... cus you weren't having a parents, not even have to pee or poop... cus you are demigod, not mortal but... you got send to Adoption Centre...
And after boring 7 days, you got adopted by Royal Family a.k.a Dreemurr's Family... And you were lucky that you were adopted by Royal parents a.ka Dreemurr's Family... but when you leave adoption centre with your parents... you see a Skeleton... A tall one... And his name was Sans... A famous comedian... There were many fangirls for him as he shot a flirty finger gun at you as you blush... And you haven't seen him again... Till...
1 year later... School is now over... and Now it's Time for Summer break for 3 month... You hadn't aged cus you are demigod, you can't age... You are still 13 years old but... You have been woke up as Mom called you to go downstairs... it was long trip cus your house was a CASTLE... but as you got to... You see A familiar Skeleton... Sans... He spoke in lazy tone as he looked at you and picked you up...
Sans: Heh, Toriel. Look how cute kid you got, heh!
Despite that... That this Skeleton is the Strongest than Everyone including all Humans and Monsters and Everything including Demons and God cus he is Fanon and only you know it... And probably other but it's just minor amount of people know... His bones and Coat/Jacket was quite soft for A Strongest one... It made you feel mix of Fear and Embarrassment as you hug him back...
