Thank you for your awesome response! Hope you don't mind doing more for me. I'm pretty much in love with this things. So how would MT and UF bros react to their s/o who has no SOUL?

{ I am glad you liked my answer~ Uhm… I assume here S/O is apathetic or they are like Flowey since he has no soul. I don’t know how to interpret it, if they are insensitive or if they sold their soul to the devil (?) I remember I answered to something similar here.I guess, for the UF Brothers the reader is an apathetic person, not their partner, uhm. While for MT I supposed S/O lost their Soul because of something… ? Then, I added also Fell! Gaster because it was funny– }

Sans thought Flowey was the only creature without a Soul but maybe he was wrong and this was a normal thing… Perhaps? Sans was not so sure about it. He had no energy to investigate and he did not care if you could be possessed by the evil child since Sans was used to it. He kept doing his job hoping you were not dangerous. Then, if you were only apathetic, he could quite understand your (no) feelings since he found himself in the same situation so many times because he was not a happy and satisfied person, and he had too much problems in his life to think his existence was worthy or sane. Sometimes, he asked himself if that apathetic state was better than feeling sentiments like sadness and rage, the ones he often perceived and that lived in his soul. Sans has already thought to end his life, fuck it all. Nothing really mattered in this planet to him. Maybe his brother, he cared about Papyrus but, sometimes, it seemed the tallest skeleton did not care about him, at all. This fact made Sans so frustrated and disappointed. He tried not to think about it so much.At the end, he ignored you and your emptiness state too, since he was busy to pity himself in his desolation to care about other stuff. He was not a therapist or a priest, neither.

Actually, he was not the kind of person who thought about that stuff.His only mission was to defeat all the humans that crossed the Underground’s lines and to bring their lost souls to Asgore. It was his duty. Then, he did not check the colour of your soul… It was something too… Private and intimate. For him, checking other’s soul colours was something gross and he was not a creep. Maybe he could act like a bastard and an insensitive person sometimes, but there were some values he respected and he was still a honourable skeleton. For monsters, Souls were a fundamental part of their lives and culture, so he had to ask your permission for seeing your soul even if you did not possess any.When you said to him you were born without a Soul, Papyrus was quite shocked because it was too weird. That sounded like a blasphemy to him. He assumed you were joking and he did not like this kind of jokes (or any other). When you asked to him to check if he did not believe you, he was a little pissed but he did anyway. Then, you had no soul and maybe you were not a human or a monster neither. What creature were you? He thought, it was some kind of disability and you had some serious problem because it was so rare and strange. It could happen to find persons without arms or legs or maybe they born with particular deformations just like those freaks you could see in a circus. You were one of them…? Since you have never had a soul.

≋ Mafia! Sans ~

Your soul was his favourite part of your body and now… It vanished into thin air.You gave no explanation to him and Mr. Blue was worried and anxious because a person without a Soul was deceptive. It was just like an ocean without any fish. If the water were dirty and polluted, no fish would live there. Mr. Blue suspected you were hiding to him something. Nobody wanted to play with him, you should have known.Then, he asked for a justification and you had to give him one before he thought you were planning something bad. Did you want to trick him?You explained to him you lost your soul and you could not find it anymore. It was not a big deal and you could keep on surviving even without a soul. Mr. Blue was too shocked and he was losing his patience but he acted calm anyway asking more details about this story. It seemed you made a deal with some evil person who promised to you something and you gave your soul in return. Mr. Blue knew you were too naive and timid for this world and maybe you have been the one to be tricked by them. Since he had a lot of connection, he was able to find that witch and they have to pay for their sins.

≋ Mafia! Papyrus ~

Since he was a very sensitive skeleton, he realized you have changed and something happened to you. Lucky Strike always pretended to be a bad guy, since he was a gangster and they had to be cruel and cold so he tried to act like that. Actually, he was so gentle and sweet especially with his brother and you. Being bad was the only way to survive in this hell. When the thug life has chosen you, you could not turn back.Lucky S. was used to see your pretty and bright soul because it relaxed him so much; it gave to him a beautiful feeling of peace and calmness. The last time he saw your soul… It was disappeared. Maybe he was losing some degrees view and he did not realize it. It was terrible since he truly needed to see well for his job. Then, you explained to him his sight was still perfect because you had no soul anymore but you did not care about it. You seemed completely apathetic. The poor skeleton was so worried and he asked where you lost it –like it was a pencil or a random thing-. He was panicking because it was so weird and he did not know how to help you. Then, you explained to him that Flowey had treated you saying he wanted your soul or he was going to kill you. Lucky S. just nodded, kissing you on the cheek. The next days, you did not see him so much because he said he had an urgent job to do but he would be here before sunset. You could image what his target was.Woe to everyone who touches any member of his family.

BONUS:

≋ Fell! Gaster ~

Gas has never been so curious and he was seeing you like his brand-new guinea pig. Such a good thing for him, but too much bad for you, poor child.You were the first individual without a soul he saw, what a weird phenomenal. He had to study you. To vivisect you if it was necessary.What were the causes that brought you in this situation? Are you born with no soul or you lost it one day? In what circumstances? It made you an insensitive person? Oh, well, very interesting. Since you could not feel any emotion, you could not feel any guilt, pity or mercy towards people because you were soulless. You did not care about anything. The world could explode right now and you couldn’t give a shit about it. Oh, and you did not care about the people who loved you, too. You were so cold and heartless. This made you the perfect weapon. You could kill anybody without thinking about the consequences and you would not be stopped by regret or fear. You were not even a human so we did not have to be worried about morality or civil rules. So, are you ready for some innocent and kind experiments? It won’t be so painful, maybe.
