Underfell Sans x Reader Headcanons
1. Red LOVES your hair like loves loves it, he loves playing with it, running his hands through your hair.
He likes brushing it and braiding it, he likes to style it anyway you’ll let him. Skeletons don’t have hair so this is a fun new thing for Sans. He’ll never cut it, he’s to scared he’d ruin your beautiful hair. But he’ll go to salons with you and watch you get your hair cut. He loves all hair lengths but long hairs his favourite as its so malleable you can do so much with it.
He’ll also wash it for you, give you that head spa treatment to the best of his abilities, he likes watching those Japanese headspa videos partly to relax and partly so he can learn how to do it on you. It takes time and practise but soon Hes a natural at it, washing and brushing and blowdrying your hair and giving you little massages.
Just be prepared for him to randomly ruffle up your hair playfully on dates, or brush a strand out of your face or beg you to wash it again after he just finished washing it.
2. Red likes cooking for you, hes not nearly as good as his brother Edge, Toriel or Chillby but he tries his best,
Reds best at breakfast foods, eggs, toast, hotdogs something simple and easy. But where his true heart lies is making drinks.
Sans sometimes works for Chillby at his bar to pay off his tab, so hes used to making drinks for the customers and has gotten quite good at making a tasty alcoholic beverage. His favourite to make is Martinis but he can make just about anything now. Even apple juice. He knows how to press the juices outta the fruit, then you add water and some sugar, and shake it all up. Then bam fresh squeezed appy juice. Even add some slices inside the container for extra effect!
Red will adore watching you eat his cooking and drink his homemade drinks. One of his love languages is Acts of Service so watching you be refreshed and relaxed from something he did makes his heart melt.
3. Being somewhere on the Asexual spectrum (haven’t decided which label yet lol) he doesn’t care much for your body in that kinda way, if you ask him he’ll gladly give you what you want ;), but otherwise hes not actively seeking it out.
Though Sans still loves to tease and flirt with you anyways, he’ll call you Doll or Dollface, Sweetheart, Sweetie or Sugar. He’ll even make up new ones like “whats up lolipop” but when hes feeling devious he’ll call you things like Pet, Mine, Bbg, or Sexy~
Tho he never follows up the teases with anything, he still loves to see the flustered look on your face. I guess somethings never change.
4. Red just loves your personality. He could listen to you talk endlessly. Even better if he falls asleep to the sound of your voice. Or you keeping him awake in the morning talking about your plans for the day, the more excited you are the more excited he’ll end up getting.
When he inevitably starts to self isolate again he finds himself missing the sound of your voice, your strange quirks, your hobbies.
He loves watching you work on things, the ways your hands move as you make things or type. The way your face furrows or lights up with new stressors or excitements. He could watch you work for hours. The determination you have to get things done is just simply admirable to him.
Before becoming a washed up drunk he was once a determined little shit to. Not on a humans level, but he had plans, goals, ambitions. But things happened and everything was lost. Now seeing you with the same spark he once had gives him hope that maybe one day he can reignite that lost spark of his own. Till then he’ll just watch you and Paps living the dream.
