Soulbound by kayixu
Sans has questions: Who are these people? Why did they kidnap him, and how do they know so much about him? In any case, they don't seem too dangerous. What's the harm in sticking around to find out? After all, his life has always been pretty weird. Why would that stop now? Sans' memory has never been the best. History's forgotten far more. Oh well, at least they have each other.

Tw: self harm, depression, and suicide themes. I told you it was venting. Stories like this have always helped me get through things, hopefully mine can do the same. Feedback would be great!
