Sansandpap cerita

I'm finally making an actual book *clapping in the distance* I only seen underfell,fellswap and cq sister scenarios so I decided to make an underswap book {the cover is mine}

This is about Undertale (again) and its when Asgore was just becoming king, Toriel was getting married to Asgore, Dr. Gaster existed, many memories. Sad. Okay? Just.Sad. In this story this is when everything goes down. Gaster dies, the king and queen break up, and last but not least, what Sans and his little brother do once their father dies.
