Undertale: My Forgotten Fantasy

(Warning: This is my first fanfic so please support me. p.s. The game undertale and the picture is not own by me, also its an AU not the original universe, so if something doesen't make sense, in this universe it does. P.s.s. I am also going to put in some love scenes, but the thing is, I don't think it's rated 18, but rated 13 since there is kissing since the main characer is a skeleton.)(A/N:My goal is at least 100 chapters.) This story is about a 18 year old boy reliving his past memories, hopes, and dreams he had when he was young. Only for him to realize that his final wish came true. With his imagination and power in his hands, he will protect his universe at all costs. Just to relive his fantasy.
