I miss you (Uf)sans x reader

 
Today you were getting ready for something big at work so you had to go to a job trip. As you got all your stuff you begin saying bye to everybody. "Hmm I hope I didn't miss anybody... Oh yeah I forgot to say bye to sans" you started walking to sans house

<At sans house brought you by Levi's epic kick>

You knock on sans door as you hear him open the door "oh.....hey there (y/n)...." Sans said kinda quiet it made you worried him cause it was rare to see sans quiet. "Sans what's the matter you've gotten quiet all the sudden?" You ask worriedly sans sighs " I.....I don't want you to go" sans said looking away kinda embarrassed you giggle "sans I'm just leaving for a week it's not that lo-" you were cut off my sans "A week that's not long? That is long (y/n)!?! I can't wait for a week it's too long" you shocked that sans said that mostly you were about to say something but then sans cut you off again "you know what? Leave just go to your job trip not like I care anymore " sans said as he slams the door in your face {aww hell naww} you looked down sad but as you were about to leave you say "bye sans I'll see you later" as you disappear through the snow.

<you went to the air port and you said bye to everybody so your at your job trip>

Sans pov
As (y/n) leaves I didn't even go to the air port to sent her off.. I feel like a piece of my soul has went with (y/n) but why am I sad I'm suppose to be happy she's gone! She's been a bother to me but for some strange reason I like her being around me. Wait what am I saying!? I can't fall for (y/n)!..but now I think about it I guess it I'm already fallen for her...as I walk out of my house I hear (y/n)'s voice I turn around to see her but she wasn't there and I then remembered she left to that dumb trip job. I sighs. "Why do you have to go when I need you the most I...I don't want to be alone" I said whispering

<a week passed cuz I'm lazy like that>

Y/n pov
Finally I can get back home! I missed everybody and bet they missed me too I just can't wait to see them again and mostly sans I bet he was sad but...I don't think he cares about me coming back...I sighs I just hope he's not angry at me...

<time pass by as you got home>

As I put all my stuff away I said hi to everybody in underfell seem like everybody was happy to see me again I'm also happy to see them aswell. I walked to sans house and knocks on his door as I see sans open the door he was shocked then he looked at me angry. I stepped back away a little. "H-hi sans how's it going?" I said nervously. Sans just stares at me angrily as he walks up to me. I thought he would hit me but i never expected sans to hug me tightly "stupid (y/n)! Did you know how much I missed you?!" Sans says angrily as he hugs me I was in total shock I thought he would tell at me for different reason but....did he really missed me that much? Sans looks at me and blush a little "hey (y/n)? I got to tell you something....." Sans said I look at him questionably "what is it?" I say "I...I like you" I look at him shock. Sans must've thought the other way though "sorry I know you li-" I cut off sans as I kiss him "I love you too you bonehead" sans grins happily as he hugs me. I'm so happy to be back " I promise you I won't go to another trip job agai" I smiled "you better promise me that your gonna have a punishment" sans said as he winks at me as I get the message I started to blush

Hope you guys like it oh and I might do a ask uf Sans just ask sans some question and he'll reply to you and I'll do it with picture too! With your question in it x3
