(G Sans x reader)

G and (y/n) both came from messed up families. Their pasts have never been shared with one another and only Frisk is aware of both tales.

Hey, girl, open the walls, play with your dolls

We'll be a perfect family.

(y/n) always told herself that she had a perfectly normal family but the reality was opposite.

When you walk away is when we really play

You don't hear me when I say,

"Mom, please wake up.

Dad's with a slut, and your son is smoking cannabis."

No one ever listens, this wallpaper glistens

Don't let them see what goes down in the kitchen.

Her father was always at the brothel, Mom never paid attention as big bro lit joint after joint.

Places, places, get in your places

Throw on your dress and put on your doll faces.

Everyone thinks that we're perfect

Please don't let them look through the curtains.

Picture, picture, smile for the picture

Pose with your brother, won't you be a good sister?

Everyone thinks that we're perfect

Please don't let them look through the curtains.

G knew what it was like to put on a show for everyone. Smile and make everyone believe that nothing's wrong.

D-O-L-L-H-O-U-S-E

I see things that nobody else sees.

(D-O-L-L-H-O-U-S-E

They saw the world in a way nobody else could.

Hey, girl, look at my mom, she's got it going on

Ha, you're blinded by her jewelry.

When you turn your back she pulls out a flask

And forgets his infidelity.

Her mother was a raging alcoholic that doubled as a gold-digger. 

Uh-oh, she's coming to the attic, plastic,

Go back to being plastic.

No one ever listens, this wallpaper glistens

One day they'll see what goes down in the kitchen.

G walked over to the house only to find her banging on the attic window. He ran inside shoving past her family. She was abused and locked in there for three days until G broke down the door. G took her back home with him, not taking no for an answer. Once he got inside, he called Undyne and reported the abuse.

Places, places, get in your places

Throw on your dress and put on your doll faces.

Everyone thinks that we're perfect

Please don't let them look through the curtains.

For the first time she saw her dearest friend in such a state of disarray.  The house was a mess, Papyrus was nowhere to be seen.

Picture, picture, smile for the picture

Pose with your brother, won't you be a good sister?

Everyone thinks that we're perfect

Please don't let them look through the curtains.

Pap moved out weeks ago because G refused to help out outside of his lab routine. G was especially frazzled while tending to the young female's injuries.

D-O-L-L-H-O-U-S-E

I see things that nobody else sees.

(D-O-L-L-H-O-U-S-E

She put a hand on his cheekbone.

"G, what's gotten into you?"

"N-nothin' doll, I'm fine" he said shaking.

Hey, girl

Hey, girl, open your walls, play with your dolls

We'll be a perfect family.

"G, don't lie to me, I know better"

G huffed in defeat and confessed about all the problems he was having.

Places, places, get in your places

Throw on your dress and put on your doll faces.

Everyone thinks that we're perfect

Please don't let them look through the curtains.

"G, why didn't you tell me sooner?"

"I guess I was afraid that you'd leave me too"

"Sans, you should know by now that I would have came to help in a heartbeat"

Picture, picture, smile for the picture

Pose with your brother, won't you be a good sister?

Everyone thinks that we're perfect

Please don't let them look through the curtains.

"Like you did?"

"I was scared of what my folks would do to you"

"They could threaten me all they wanted to but, I'll be damned if I let them cause you any more serious harm. You got that, kitten?"

D-O-L-L-H-O-U-S-E

I see things that nobody else sees.

(D-O-L-L-H-O-U-S-E

I see things that nobody else sees)

"Yes G, I understand" she kissed him on the forehead.

"Good. Oh and (y/n), one more thing"

"Yes?"

"Don't call me Sans ever again"
