This is a theory about how all of the Ateez Music videos connect, and the story behind it. So if you find that stuff interesting, this '' Book'' would definitely be for you. I've made this theory myself and I have not read any other theories. So if anyone has made a theory similar to this, then either this theory could have huge potential since other people find the same evidence, or it's a huge coincidence. REMEMBER THIS IS JUST A THEORY. (If you do find this theory as a realistic option, please vote and comment so it'll be easier for other Atiny's to find)
