Painted Rose ~Undertale and RWBY crossover~

I know that there are way too many of these on the site and you're probably getting tired of them. I just couldn't find one that had what I wanted so I made my own version. It is not an xReader book. I will not be shipping RWBY characters and Undertale characters, though there will be Sanscest. Also, no genders will be changed. There will be a part in the story where you can interact with them as the Creators(Ink) or Voices(Error).
For those of you who don't know: these stories usually contain abuse and triggers.

Young Sans Rose has been abused and Neglected ever since he could remember. One day, after a tragic accident, he decides that he has had enough and escaped. He wakes up in a strange room and from here on out he discovers the Multiverse also adopting a new name: Ink. He went on adventures and defeated(Befriended) his enemies.
After years of happiness he returns to his former home. Getting stuck in the process. Unable to leave he has to relieve his old home from a threat.
Will they Prevail?

I hope you like this!
