After Frisk had free the monsters from the Underground the humans are having trouble trying to adjust the monsters living among with them again. The monsters love having the freedom they dream and hope to ever have. Yet another boy come into the monsters lives as he is adopted by Toriel and becomes a brother to Frisk. Yet strange things began to occur as well for someone or something in Sans and Frisk dream and talking to the boy. Who is this mysterious monster and what does he want?! P.S. I'm having an OC involved in the story and Frisk is going to be a non-gender though out the story so there will be no conflict to rather Frisk is a girl or a boy. As well Chara is a female in this story. Thanks!
