What do your husbandos think of your monster form? And do they have themselves a human form?
Uf!sans/Chops: If food ended up left outside the house, it’d be gone. After the first couple of times it happened, little gifts would be left for him. Coins, or charms, random cords or tech parts. He looked it up, discovered crows tended to do that sort of thing and figured he had some bird friends. He definitely freaked out about it. But after realizing that she’d been the one leaving behind gifts he sort of continued the trend and leave her snacks, and she’d find things he’d like and bring them to him. She eventually started tagging along with him to walks to the store, and then he’d let her come in the house and see what he was doing, and eventually he figured she was just living out in the forest and was un-registered. So he let her stay.
MF!sans/Doom: Basically dropped by the house and unintentionally found her and because he didn’t know what was going on he assumed she was a burglar not his other self’s friend/roommate. He tried to catch her, but she got in a tree and by that time Chops came back and explained. Doom apologized but… Uh, She didn’t especially like him before Chops did a little convincing. He was brought into the idea that she liked snacks, and that if he wanted to get on her good side he should bring her some. And eventually they became closer. She was especially curious about stuff as she hadn’t been near humans in a long time aside from Chopper, so he helped educate her on humans and culture.
HF!Sans/Saber: Eventually Munster stowed away with Chopper cause she wanted to hang out with him and she ended up getting left behind at Saber and Dire’s house. Saber found her, fed her, and let her do whatever she wanted - supervising her of course. He thought she was weird, and resonated with her spiky toothed spooks.
BUT YEAH, thats what they think of Munster, and the soft squishy boi’s as humans.
