Ok I'm still working on it but
There's this girl with the username GrassyOwl4 (but we'll call her Gr4ssy). She's like 16-17 btw. She's playing Roblox and stuff, when she says smth like "man I wonder what it would be like if I ever got to relive Roblox in the early 2000's/2010's". And then smth weird happens and she's basically sucked into the game. Not only that but she's also time traveled to the year 2009 (or 2012, haven't decided yet). She's in one of those games that has a house like this (see the image or smth). She meets some other guy named MoonStriker89 (we'll call him Moon). The two quickly become friends and stuff. Weird stuff happens later on with the world/game and basically Gr4ssy finds out Moon has some sort of secret. Long story short he's basically evil and has been corrupted by the world their in because its evil and stuff. In the end Moon and Gr4ssy merge, becoming one evil being or smth. Again, I'm still working on this lol so it might not be THAT good yet.
