Before we begin, all of you voted for 1 so, it won I guess. I will add it later once I finish this chapter,I will start tracing it. This is a sans x jealous reader. Now, let's get into it!
✂-------------------------------

Your pov

-will you be my valentine-

You crumpled the paper and threw it beside the trashcan with the other crumpled papers. You groaned and held your head in frustration. You were trying to make a Valentine's card for sans, your crush. It started when you met. You just looked and Bam! There! The cupid decided to hit you with his arrow. You had already tried this 36 times! This is your 37th fail and you still can't do the perfect one! "How will I do this?" You groaned, clearly confused and annoyed. Then, you got an idea. You shot your head up and started to write, careful not to mess up.

There! You were finally done! (This is not great considering I'm not great at val cards but, I gave it a shot)

Dear Sans,

Happy Valentine's day sans! Listen, well read, I know this is sudden but I just want to say that I like you. When we first met, I already fell for you. You were just, perfect. I just hope you like me back but I'm not really saying that you should like me, I understand if you don't. Please be my Valentine.

-(Y/n)

It is still not the best but, you gave it your shot. It's better from the other ones. You added design to it and tied it on the gift box. It was a red box with a blue ribbon. What was in there was a black hoodie, a ketchup bottle (of course), bunny slippers and soon there will be Chocolate. You will put it when you are going to give it so it won't melt. You stretched and jumped into bed after putting on your PJ's. You had been doing that from 5 to midnight so, you need sleep. Besides, you already done your routine. You snuggled under the covers and fell asleep.

You woke up to your alarm. Today was Valentine's day! Then you hesitated. What if he doesn't like me and start ignoring me when I gave this to him? What if he gets angry at me? What if... "Honey! Breakfast is ready!" You jumped. "Coming mom!" You changed into your attire and ran downstairs with the gift in hand. "Aw! Does my little girl have a boyfriend?" Your dad teased as he took a sip of his coffee. You blushed. "Dad!" He chuckled as you sat down. A plate of waffles with chocolate syrup and a strawberry on top was sitting in front of you. You ate it. "Careful dear! You might choke!" "Mom I'm not a kid anymore." You said, mouth full. "It's rude to talk while your mouth is full." You gulped the waffles. "Dad please!" You finished your meal, drinking your milk (gotta have it) and ran to the fridge, getting the chocolates and putting them in the box. You ran out. " Bye Mom! Dad!" "Bye sweetie!" You got on your bike and cycled to sans and Papyrus's house.

You finally made it. You looked in the window to see frisk hand a card to sans. You got jealous. Frisk was an adult. Sans might have feeling for her, not you. You sighed and knocked, trying to not just barge in there and maybe kill frisk. Speaking of, she is the one who answered the door. "Oh hi (y/n)! What are you doing here?" "W-well umm... I'm just here to say hi and happy Valentine's day!" You smiled. Why can't you give it to him now? "Oh! Happy Valentine's to you too! Do you want to come in?" "Sure!" You got the gift box and went in, putting the chocolates in the fridge. "Who's that gift for bud?" You froze for a second, not only that he saw but the way he called you bud, you felt friend zoned. "U-ummm... N-nobody...?" He looked at you with a suspicious yet confused look. You put the box on the fridge and sat on the couch in the living room, getting fidgety. Sans sat on your right while frisk is on your left. You put a couch pillow on your lap and put your hands on it. The TV was turned on and you all watched. "So, where did papyrus go?" "He's with-" before sans can finish, you see papyrus in a live show with mettaton. "Mettaton..." He growled. "C'mon sans, let him do what he wants. He is already an adult." You smiled reassuringly, making him blush a little but he looked away. "But you already know that rusty bolts, always flirty and he might hurt pap's feelings. If he did, I swear I will-" "sans thats enough." You put a hand on his shoulder. "I'm gonna go get some water." You stood up and went to the kitchen. You drank a glass of water. You went back to see frisk laying on sans's lap, asleep. You were fuming in jealousy and anger but you held it in and took a silent breath in. Sans seems to be deep in thought. You sat on frisk's left and watched the TV, trying not to grab a knife and stab frisk straight in the chest. "Hey, let's go to the park. There might be some booths there." Sans said. "Sure." He shook frisk awake as you walked out of the door, bringing the gift just in case. Sans walked out and faced the door. Frisk fell down on him 'accidentally'. It looked like she did it on purpose. Sans blushed while you were really, really angry. You got on your bike and they both got their respective bikes. You all cycled to the park. You saw the entrance. It had many paper houses on it and there was some hanging there. You saw a lot of people inside and a few booths. You all parked your bikes and went in. You saw a photo booth. "Let's go there sans!" Frisk shouted and pointed to the photo booth you were just talking about. You all went inside. You inserted a few pennies and you prepared for the shot. First, you did nothing and then did a few poses and messed with the accessories

(2 lazy 2 color it)

You all got out, laughing. "I-i can't believe you dressed up as a cat!" "What? It's the purrfect one!" You all laughed. "C'mon! Let's go to other booths!" You said as you all ran.

Timeskip

No one's pov

"Gotta go! Mom might be angry at me of I don't go now!" Frisk waved goodbye and ran to her bike. You sighed. "U-ummm... Sans?" "Hmm?" He looked at you. You shoved the gift box to him and ran to your bike and cycled back home, clearly embarrassed. Sans chuckled. He took the card and read the letter. He blushed but smiled. "Why didn't you say so in the first place?" He opened the box and saw all the things you gave him. He smiled. He teleported back home with his bike, a genuine smile on his face. "This is the best valentine's I had ever had. To get your crush to confess to you? Best day." He laid down on the couch, putting the gift down on the table first. "Love ya too (y/n)."

Sry if it sucks
