Forever Happy

Frisk is living a happy life with their friends/family, the monsters! After book one in this series, they have been spending much time with Asriel and Chara as they have bonded closer with each other. Suddenly, Frisk starts acting suspicious and Sans decides that he must spy on them to make sure they're okay. What will happen when someone from Frisk's other life clashes with their new one?

This is the second book in my DETERMINATION series, please read the first one before this which is just called Determination- An Undertale Fan-Fic.

I do NOT own Undertale but I do own this plot/story. Thanks to Toby Fox and the Undertale team for making the best game ever!

Hope you guys like this story :)
