This fanfiction essentially deals with timelines present in the game Undertale.
It'll be genocide-ish and reminiscent of that route in particular.
Main characters include: Chara, Sans, Asriel/Flowey, and of course — Frisk.
The pronouns for Chara will be he/him, Frisk will be she/her. When the two are interacting, the they/them pronouns could get mixed up, so I chose the precedent.
If regular pronouns aren't your thing, just don't read.
Oh, and if you're uncomfortable with gore...
"Perhaps another path would be better suited." ;)
Also, this fanfiction has been exported here from my Wattpad version: "Control." For best reading experience, I'd recommend you to read it on there, as this fanfiction contains pictures and gifs most of the time.
Proceed with determination.
