[Y/N] lived with her adoptive mother Toriel for a while. How long is that? About three years. Throughout the time, the monsters in the Ruins know her as if they were her siblings. 

Flowey became way nicer each day around her, losing his soulless behavior. He cares about her so much he promise to protect her. 

All was well... 

Until she sneaked out of the Ruins. Going from Grillby's to the Librar(b)y, she went around having fun. Laws did apply, 16 being the age to leave past curfew, 18 being the age to finally date, and 21 to legally marry. 

One day, I slipped from my own mouth of the presence of a Princess...

And Asgore ordered the Royal Guard to break the door to the Ruins...

You've been doing the same True Pacifist / Pacifist Run over and over in a place called the "Underground". Though you like the Underground, you can't help but feel weary.. Every time you [SAVE] everyone, the World just..[RESETS]... And with that, you're back at the beginning again. You just want to go home... Why won't this "Underground" let you leave? ... Well, if you can't leave... Something 'new' should happen sooner or later, right..? (You hope that something exciting or different will happen in the Underground.) (You are filled with DETERMINATION.) --- ;) ~~~Disclaimer: I don't own those (MULTIPLE) pictures used in the Cover. I just mixed them up for a spicy cover. ( ͡° ͜ʖ ͡°) Mash-up covers are the best. ;') (I spent up to 3 hrs mixing stuff around + editing + adding light and shadows...*Dies*) If you have a problem with the Cover, I'll change it.
