For the longest time you were traveling through different universes trying to get back to your home universe, but you're lost, doomed to be traveling in foreign worlds forever, you even lost all of your memories, all you remember is your own name.

You got attacked by Error Sans. He brutalized you for his entertainment. As he was about to finish you, you were transported to a white void with a monochrome girl standing over you.

It's okay, you're safe now. You will forever be in my care...
