Friday Night Funkin’ Soft does not stay within canon by any means. It’s a remix of the base story and even though the characters are counterparts/based off of the ones you are familiar with, should not be expected to stick with said canon.
Friday Night Funkin' Soft is a remix of the original game with a new story, new characters and revisited songs. FNF Soft takes the basic formula of Friday Night Funkin' and adapts it in its own way with a more complete narration, an original character design, new backgrounds and great musical creativity for the remixes. Discover the story of Soft Boyfriend who tries to realize his dream of becoming a painter. He will meet many other characters who will enrich the storyline and who will of course have to be beaten during rhythmic musical battles. Everything seems so perfect and innocent in the world of Friday Night Funkin' Soft on the surface and yet the encounters you are about to make will all be more amazing than the next.
