So I was really inspired to keep writing stories by someone who commented on one of my stories. You know who you are. I've been on here a lot and I've seen people actually reading my books... I'm so happy ^_^ Anyway... A backstory and How to read an X reader will be the first chapter... This'll probably end up being a lemon cause, that's all I know how to write... xD So... Enjoy!

You are about 15, Gaster is 17. In this Gaster is an older brother to Sans and Paps. Asriel is about 6 along with Frisk and Chara, who show up later. You and Sans are best friends, but Gaster is amazing! At age 17 he is the royal scientist and you hope you can help him out.
