Y/N)'S POV (WARNING MIGHT TRIGGER PEOPLE DON'T READ FURTHER IF YOU THINK YOU ARE)
 
Hmmm.... I Wonder Sans is doing....he's been acting strange lately.I'll look up videos on YouTube to pass the time.'I thought as I got out my(favorite phone) laid down on the key lime colored couch and looked up you tube videos concerning undertale. (Pretend undertale not a game for reasons okay.....). After looking at videos that we're hilarious (not cringey) but you scrolled down to see a certain video.....with Sans smiling but crying.....'What... Why is Sans sad' I felt my heart drop at the sight I read the title out loud "The secret behind the smile" he's been pretty off lately I might find out why....'

I Had no idea he's been in so much pain..... I thought crying quietly "Why.... Why didn't he tell me he's been going through this and by himself." I said whispering to myself. I should have known. Then I here the door open,'oh It's Papyrus..Hey I have an idea!' "Papyrus" "YES (Y/N)" he said completely closing the door behind him. "Can you help me with something....." I said twiddling with my thumbs "SURE WHAT IS IS" I looked down at the floor and said "I was planning on throwing S-Sans a surprise party...and I was wondering if you'd like to help....." Looking back at Papyrus for an answer his "eyes" glistened with excitement "I THE GREAT PAPYRUS WOULD LOVE TO HELP YOU WITH THIS PARTY FOR SA-" I put a hand we're his mouth would be because Sans walked in the room."heya paps', (y/n) what are you talking about" "Nothing~ hey you know what maybe you should visit Toriel-er-I mean goat mom umm-see you later Sans" I said pushing him to the door. "Hey wait a minuet......" Sans lifted me in the air"Gah! " for a skeleton he's pretty strong.  "I have the feeling your hiding something from me (y/n).... " 'not like your hiding either.... ' "Toriel asked if you could come over, she said it was an emergency " I said sounding worried "....In that case I'll be on my way over, see you guys later, bye" Sans said winking before he closed the door and left the house. I sighed "now I need to call Toriel and tell her about operation "Get Sans to smile big time" "REALLY (Y/N).... THATS A GREAT NAME FOR THIS PLAN.WAIT WHAT IS THE PLAN.." Papyrus said confused. "I'll tell you when I'm explaining to Toriel, okay?" I said as I was dialing her number. "OKAY" he said smiling a big smile. *Beep* *Beep* "Hello my child how are you doing?" Goat mom asked politely "Well I need you to distract Sans for me because we are throwing a party for Sans, can you do that please" I practically begged her.  "Of Course that is if you can tell e
me about your plan." She said excitedly "Yes,okay... " you started telling Toriel and Papyrus about operation "Get Sans to smile big time",which was 1.To get Sans out of the house and somewhere far away 2.start to prepare party things like streamers, tables food etc. 3. Get and blind fold Sans 4.Party!! 5.Show the surprise. "There did you get all of that Mom." "Yes I did and I think he's here already I got to go. *Beep* "Alright Let's get started! " I yelled fist pumping in the air.
*Time skip*

*Sans pov*
It's been over an hour since Toriel and I been catching up with each other. "I wonder what (y/n) and Papyrus is up to." *Beep* *Beep* "Wait a second Sans I need to take this call. "Okay Tori." I just slumped in my seat 'man I sure am tired'  "I-is that all okay I'll bring him over" Toriel said hanging up. "huh?" "Sans, (y/n)'s in trouble" Toriel expression turned very serious. I stiffened when she said that."S-she's in trouble w-what kind of trouble " "I think we might want to hurry so we save her-" I immediately got up and started to drag Toriel. "Where are they?" "In front of the ruins she said she sounded scared.." 'That's It !!' I teleported me and Toriel in front of the Ruins and- "SURPRISE!!!!!" Papyrus yelled in, showing me with a table of various foods an ice sculpture in the shape of a well designed heart and a huge present....."Th-thanks but where is (y/n)" said worried I stared to looks around for her... Nowhere but I didn't check the big box... I cautiously step towards the Box.....and slowly opened it an "SURPRISE SANS!!!"  (Y/n)  screamed as she popped out the box scaring the living crisis out of me"(y/n)?? What the heck?! You had me so worried that I was going to search the entire underground for you" I slapped a hand on my mouth, and blushed.
