I’m the one who asked you if you could make other characters than the skelebros, and since you told me you could, I was wondering if you had thought about how Underfell and FS Grillbys or Gasters would have acted towards a really sensitive and compassionate S/O? Of course you can do whatever you like, if you don't want to write about them, it's okay ^^
Oh, this is an interesting one! Now I only have my versions of the characters to go off of so it may be a bit different from others interpretations. But here you are friend;
He's probably the most mild of the others. He's protective of his S/O so if someone manages to upset them, let's just say they'll end up with some burns- he's happy to have his S/O around the bar and nightclub whether they're up at the bar with him or doing their own thing at a table or booth.
He is happy to take a break from working to sit and cuddle if his S/O needs some cozy cuddles. He'll take of his jacket and wrap it around them while they sit together. His S/O comes first even if it's a busy night all they have to say is they need some love and he'll happily provide!
He's a big flirt and likes to see his S/O fluster but he'll stop if they don't seem in the mood. If something upsets them he'll try to avoid it but he isn't perfect so he'll slip up sometimes. He tries his damnedest though to keep his S/O happy, or at the very least make sure they aren't crying. He kind of shuts down when they cry, he wants to hold them but also tears kinda hurt being a fire elemental and all. But he tries to make sure it never gets to that point.
He... To be blunt, he's an asshole. He doesn't necessarily mean to be, but he comes off that way most of the time.
He gets very caught up in his study's and experiments to the point where he won't sleep for days, making him cranky. He will get mad if his S/O tries to take him away from his work, but he'll snap out of it if he manages to make them cry. He will mutter a comment on how they can't get upset over everything before he stops what he's working on and hugs his S/O close. He'll often pause his work and go lay with his S/O. Which will always end in him falling asleep clung to them with his face nuzzled into their neck.
He is horrible at reading hints, despite being a scientific genius he doesn't catch onto the signals his S/O gives him. They've been talking about how much they like cuddling on the couch or laying together? Trying to get him to initiate some time together? He'll just respond with "Glad you like it." and go about his day. He needs direct directions stating that they want something or he won't catch on.
He loves his S/O and how sensitive they are! It's just means if something just happens to scare of upset them they'll come running to him for comfort! So who can blame him if he leaves things around to startle his S/O into coming to him?
He's happy to cuddle with his S/O! And if they're upset he'll have them go pick something to watch while he gets started on making their favorite dessert! Then he will build a pillow fort to watch what his S/O picked out while they eat and he cuddles them in his lap.
He is never to busy for his S/O. He likes to both give and receive physical affection so his S/O can expect lots of kisses, cuddles and hugs! Along with tea and sweets whenever he feels is needed. He's definitely the most clingy and affection of the four.
He's a bit hit or miss. He either wants to be around his S/O and be really affectionate and loving or wants to be left alone to work in silence. He's not the best for an S/O who needs a steady stream of love and affection. He sees no issue with his actions and if brought up hell shrug it off.
Even if his S/O is upset or needs some TLC he will brush it off and just tell them maybe later. His personality can be considered rather cat like. Things are done on his time. And if he's done he's done.
But even when he is busy with whatever he's working on his S/O will find sticky notes left around the house with little things like love hearts and reminders that "he loves them" as well as the occasional cat doodle.
Hope you enjoy! Once again this is my interpretation and is in no way canon to the official AU's. Feel free to send in imagines and I'll get to them when I can! <3
