I want to go home.... (Undertale AUs x Reader)

You're Frisk's friend, who jumped down the Underground. Not wanting to leave him alone, you jumped after him.
After a lot of pacifist routes and resets, you woke up in a place which seemed to be the ruins you knew, but soon you realized that you were wrong.

You'll switch between different AUs, everytime something serious happens. Like a reset or you die. Or even something else happens?

(Y/N) = Your Name
(H/C) = Hair color
(E/C) = Eye color
(S/C) = Soul color (everything except red, becuase you're not determined)
(F/C) = Favourite color

This is my first fanfiction, so don't think too much of it. Even though, I don't think that anyone would ever find this. XD
