[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.

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...

Is it just me, but when your like in a hammock and you're being rocked, it's really relaxing
In my mind, I thought the text was going to say 'Bitch, really?', but then was like, 'B-scotch...'. I thought about it for a moment, then realized it meant butterscotch....sorry!
