I want to make a series of explaining ALL LEVEL of the backrooms and this is like a introduction for everyone first time knowing the backrooms. I hope I can write some story while explaining the backroom so you can treat this as the first episode of my backroom series (story) as well. Thanks for watching! If you want to know more about any level, please let me know in the comment!
