----Insanely In Love----

Before you fell into the Underground you were a doctor of all sorts. You got to help all sorts of people too. Some polite others not so much. 

But one patient...was a child. 

They had brown hair, red eyes but kept them closed, and wore a purple with two pink striped sweater, shorts, and sneakers. Their diagnosis was split personalities and they were sent here for killing a dog without any mercy. You were creeped out by your patient and never really expressed any emotions to the child.

You lived in the Underground for half a year now and started working alongside Toriel and Alphys. The two main doctors at the asylum. You were working with Toriel when she said that she wanted you to meet a patient and wanted your thoughts. You walked down many corridors. Some quiet, others not so much. 

You both finally arrive at the one patient she wanted you to meet. You look into the blocked-off room and see a skeleton sitting in the corner. "Sans I've brought a visitor to see you. Can you please come to the glass?", Toriel asked. The skeleton flinched and then turned around. He waddled up to the glass and looked between you and Toriel. 

"Hey there, my name is (Y/n). I'm a doctor here in this facility. Ms.Toriel asked me to come and hang out with you and stuff. Hope you'll corporate with me and we can have a good relationship in the future." He looked at you and his eye lights changed into stars. "Hi! I'm Sans and this is my bro Papyrus. You're really pretty. I hope we can be friends." You started to blush a little and you nodded your head in agreement.

"Sans may I come into your room. I am going to view how you act and stuff like that. This isn't an experiment or test just studying. Ok?" He nodded his head repeatedly before backing away from the glass. You look to Toriel and she opened the door for you. You walk over to Sans' bed and set your stuff down. You take your clipboard and pen with you and stand in front of Sans. He was taller than you by ahead. He was wearing a straight jacket that wasn't strapped to him, the sleeves were hanging loose. He had bandaids on his forehead and a couple on his cheekbone. 

"Sans I'm gonna do a physical exam on you. So can you please take off the straight jacket for me?" He hesitantly nodded and slowly took off his jacket. When it was off you started to look him up and down. He had scratch scares all over his ribcage, arms, and scratch marks on his upper backbone. He had a couple of fresh wounds so you asked Toriel for some bandages. You pulled up his pant legs and checked his legs and they even had scratch marks all over. 

You sighed and asked, "Sans did you do this to yourself?" He nods his head and looks the other way. "If you don't mind me asking, why do you do it?" He looked back at you and then looked down thinking. He looked the other way with a gloomy expression. You sighed and took the bandages from Toriel and started to wrap them around his ribs and upper backbone. When done you told Sans that he could put the jacket back on. You stood up and started to write on your clipboard. 

You started to ask Sans a series of questions involving who he was, what he did before he came here, and who his brother was. You then asked Sans if you could look at his soul. He started to have a blue hue appear on his cheeks then looked at Toriel looking at her in a confused manner. 

She then beckoned you over and she explained to you why he was blushing. You started to blush yourself but coughed and went back into the room and asked Sans to take out his soul but not in the way he's thinking. "It's to see the condition of your soul. So please refrain from thinking anything unnecessary." He nodded his head and summoned his soul. 

It was a bit cracked down in the middle but not too severe. It was mainly glowing blue along with a light orange hue around it. "Tori you might want to come and look at this." She comes in and looks at his soul. Sans starts to panic but you reassure him everything is going to be fine. He still looked concerned but stayed calm for you. Tori looks at it and has a questionable face. "Sans, dearest, what color was your brother's soul?" He looks at you while you keep looking at his soul. 

"It was orange and he was super cool too. Right bro?", he asks looking over to nothing. "Tori I don't think Sans is crazy. I think he's being possessed or is sharing the soul of what's left of Papyrus." She nodded her head in agreement. "But he doesn't need to be here any longer. He seems to be fine. He should still be watched over by somebody for a few months and see how he takes things." Toriel nodded in agreement before saying, "He should stay with you, (Y/n). He has taken a fondness towards you even though he met you today. I think he's going to do well as long as he has you by his side. You can have the next few months off but keep me updated on what happens." You nodded and took Sans' hand and led him out of the room. You both checked out and you headed back to your place out in Snowdin. You unlocked your door and had Sans sit on the couch. You plopped yourself down next to him and turned the tv on.

1 year later:

You and Sans had lived together throughout the year.

You started to work again and got back late sometimes. And it was one of those nights. You got home and were about to face plant into the couch until you saw Sans 'sleeping' on the couch sitting upright. "Oh Sans what am I gonna do with you? You gotta stop waiting up for me." 

You sighed and walked into the kitchen to get a late-night snack in before going to bed. You decided to make yourself some ramen. While it was in the process of making, Sans had woken up and silently walked into the kitchen. You were in deep thought until you felt a pair of skeletal arms wrap around your waist. You gasped and started to blush. "Heya, whatcha doin up so late?" You sighed and said, "Another drill and more patients to write papers about, you know the usual. Sorry, did I wake you?" He shakes his skull and removes his arms from your waist. He moves away from you and sits at the table. You sigh in content and finish making your ramen with your face going down from the redness.

You sit down at the table and start to eat. After a while of sitting in silence, you both got up and headed towards your bedrooms. Once in your rooms, you decide to take a shower then head off to bed. Sans laid in bed thinking about you. You got out of the shower and got dressed. You exit the bathroom and get in bed with Sans. "Hey, Sans I'm gonna take off tomorrow. How about we go out?" He nods his head tiredly and starts to cuddle up to you. You smile holding the somewhat innocent skeleton. He still has yet to understand a lot.

You wake up to Sans talking to himself in his sleep. "I love you, (Y/n). I will be with you forever and always." You smile and hop out of bed. You get dressed and walk back over to the bed and kiss his forehead. You exit the room and head over to the kitchen. You make (f/f) for breakfast. While making breakfast you feel the familiar skeletal arms wrap around your waist. "Morning Sans. Hope you slept well." He hums in response and releases you and sits down at the table. 

You finish up making breakfast and sit at the table with Sans. "So what would you like to do today? I want to make today all for you Sansy." He looks at you and then says, "Can we watch movies and cuddle all day today. I don't want to go anywhere." You nod your head and both of you finish breakfast. 

You sit on the couch beside Sans and ask what the movie is. It's your (f/m) and on the table in front of both of you is popcorn, drinks, (f/s), and the remote. Sans lay down taking you with him and cuddling you. You press the play button to start the movie and you both watch it. 

When the movie is over you both sit up and Sans says, "hey this morning you missed." You faced him confused until you felt your lips being pressed against teeth. Your face erupts into blush. You kiss back and after a couple of minutes, you pull away for air. "Heh, you sneaky skeleton. You were awake the whole time." He chuckles, "Yup. And I've been meaning to say this for a while. I love you, (Y/n). I hope you feel the same way. I understand- mph!" He was interrupted by lips being pressed against his teeth. 

You pull away giggling, "Of course I do ya silly skeleton. And you already told me this morning. I love you Sansy forever and always." He chuckles and both of you go back to cuddling for the rest of the day.
