◘Created : February 12 , 2016◘

You are a small child whose living with your Mother and your Father. Your parents would always fight and you couldn't take it anymore. One day , you snuck out of your house and went for a walk around the legendary Mt.Ebott. The legend says that when a person climbs the mountain , they never return. Ignoring the legend , you keep taking a walk around the mysterious mountain. Finding a giant hole in the middle of the mountain made you trip and fell down inside the hole. Things became weird when you fell down. Two obsessive skeletons are after you...What will you do? Will you stay? Or will you leave?

I do not own Undertale , all credits go to Toby Fox and some of the people who helped him create Undertale.The story is based on a game titled Undertale but in a Yandere form.I also do not own Underfell , all credits go to the respective owners.

I love the story, but to tell you the truth when you said "other skeleton" I literally thought of Papyrus. I love that you included other timelines and an alternate universe. XD
