Ashley moved and it was the best but worse day ever why read to find out

The old bookstore wasn't your home anymore, you finally realized. It was with them. It was with him. (Sans (Undertale)/Reader. The story takes place in second person view. Reader is not Frisk!) (art is by @Elmer_Heiji on twitter)

So, Frisk set all the monsters free from the underground and they're becoming the ambassador for the monsters. And in this story Sans happens to be Gaster!Sans due to a 'accident' that is the cause of Gaster's death. And you're like forced to protect the 'gang' (Frisk, Papyrus, Gaster!Sans, Flowey, Undyne, Alphys, Mettaton, Toriel and Asgore) because you're a S-class assassin (S' means special, very special) that is not used to this shit. So I am very sowwy if my story is crappy or what evs' because this is my VERY FIRST story that I've manage to type down and share....And I might add some LEMONZ but there not going to be soo good... so don't expect anything from me....kay'

W.D. Gaster, the royal scientist for King Asgore. He has done many experiments, most being successful, though some ended in failure. This time, Gaster has been working on an experiment to create living monsters! He has been successful once, creating a beautiful child with wings that he wishes to give to the king. The second time? Two skeletons, brothers, his sons... Follow the angel, (Y/N) throughout her journey. From her childhood with the skele-bros, to her returning from a long mission from the king.

The barrier was lifted, the monsters were free but not accepted; hell broke loose, the wars were resumed. The monsters had no choice but to retaliate to the human's advances. Resources were scarce, the earth seemed unhabitable and the only way to survive was through violence. You lost all hope when you were forced to comply to such vile doings; being left alone by your family loosing them to a friendly fire during an escape. You were all alone; until he came along. ☆Violence, Cursing, Sexual Themes☆ ☆Gender-Neutral Reader☆ ☆Slowburn☆

I was walking home from my friends house one day when all of a sudden I felt something wrap my waist, next thing I know, everything went black
