A Lovelytale

This is a whole au in which one reset changed the whole ending of Frisk's run through the game. In this the true ending is achieved and Asriel is saved but in the process of breaking the barrier it resets the game to where Frisk fell but all of the previous events happened. In this reset Frisk can't access the save files nor reset anymore and surprisingly the barrier never fell.

Not to mention YOU are in the game as well but some time has passed and you come across a lot of rather shocking discoveries.
