Sans was sleeping in a sleeping bag with a few blankets in Eijirou's room. He didn't plan to stay in this human ruled world for very long so he wanted to take up as little space as possible. He also wanted to help out around the house. So he helped clean and cook and Ichika was teaching him the currency of Japan called yen so he could do errands outside the house. He was on a run to the convenience store to pick up more soy sauce.

The week prior, Ichika thought it'd be the greatest idea to make Sans go to school. While he was correct in saying there was barely anything they could teach him, he continued to go to school, only for Eijirou's sake. Ashido Mina, Eijirou's new best friend, started piling confidence on Eijirou like no tomorrow. It's a slow process, but progress is there and showing.

He got back to the house to see it completely void of life. Almost. He could hear the three humans upstairs in Eijirou's room. Sans chuckled and started going up the stairs after his shoes were neatly left in the genkan.

Sans - "Hello? What are you three doing in there? Can this wayward skeleton assist?"

Eijirou - "Welcome home Sans! Get in here!"

The younger ravenette yanked Sans into the bedroom. Sans almost dropped the shopping bag when he focused on the room before him. Two beds, one inspired by the hero Crimson Riot, the other galaxy themed. A matching foot locker at the foot of each bed. Two dressers against the wall. A minifridge in between both heads of the beds.

Ichika & Eijirou - "Surprise!"

Natsumi - "Ichika says it's going to be a while before she figures out how to send ya home, so you better get comfy with this crazy ass family."

Sans felt his chest constrict some. He was...happy? No, it didn't fit with what he was feeling. Confused as to why the human family he met mere months ago would voluntarily treat him as the son/brother that never was. A sense of fear that he would forget his roots back home if he got too comfortable in this new world.

Disgust at himself for the pang of gratitude towards this "crazy ass human family." Nauseated that he was having the time of his life in a short few months with real food while his family and friends were barely surviving off of plants and whatever fell into the Dump. And finally mourning that there was a possibility that he would never see his family again.

The anxiety-inducing thought was enough for him to clutch onto Papyrus's scarf and smother the tears growing in his eyes.

Sans - "You...really didn't have to do all this..."

Bright blue luminescent tears started falling down his cheeks. The scarf couldn't catch them all. He could feel the pleasant mind numbing feeling of Natsumi's quirk. She smiled at him and pulled him into a soft hug.

Natsumi - "Sans, you are a child. You shouldn't have to worry and be so afraid. Until you're able to return home, you'll be a welcome addition to the family. And as a family, naturally you need a place to properly sleep."

Ichika - "Exactly sweetie. I'd hate to see your grades slip because of bad sleep."

Eijirou - "Heck yeah! You'll be my cool big brother until you go home!"

Sans spent the next hour crying in the arms of his second, human, family.

<~>

Eijirou - "Ugh! Sans! Pick up your sock! How are there so many left ones?!"

Sans - "Lol, no sir-ee-doggo Eij. It's a no-bones day."

Eijirou - "What does that even mean?!"

Sans - "And that's just a theory -"

Eijirou - "Don't you da -"

Sans - "A game theory! Thanks for watching!"

Eijirou - "I swear, I'm gonna draw on your face while you sleep!"
