Summary
after two years in the ruins, you have finally decided to leave it behind and explore the rest of underground.
you're not leaving forever, obviously, you were going to return before dinner.
you're bound to meet some interesting people, make friend and maybe something more.A/N:
this is my original au called fallen soul, you can follow the canon timeline on tumblr under @fallensoul_avtfol
the fic starts from the 4th or5th arc of the story, centuries after gaster's fall.
this au is inspired by underfell and timetale, but honestly isn't that much like them anymore.
it's mostly a au about emotions, grief and letting go and healing.
there will be a lot of angst and a lot of feels.Series

Summary
In which Gepard and Sampo fall for each other much later than they would have liked.
It begins with mutual attraction - admiration on Sampo's part and curiousity on Gepard's. But a shaky foundation can't hold up the stage for great romance. Thus, I give you a story of two fools finding love.

Summary
Gepard Landau and Sampo Koski had a non-platonic whatevership (they never truly define it) until one night it all came crashing down when Gepard said something he truly didn't mean out of frustration and Sampo dissapeared for a whole year leaving no traces behind.
Yet they met again one fateful morning to solve the dissapearance of a citizen in the strange back alley of the overworld nobody even knows exist.
As if the universe is telling them to speak their truth, they got caught, arms tied together and are force to figure out a way to escape (or at least sit waiting for someone to come and save them). Silence didn't last long as Gepard opened his mouth:
“Where have you been for the past year?”
