Yep. Undertale obsessed, Minecraft addicted, ever loving creepypasta me.
Lol. Im a hard æßß-betch with no concern for anything else except....
                              ( lol. Kill me pls.)
I sometimes question toriel. She said that she will destroy the door but does that mean that the door will just be broken and we can still go through?
