Honestly? It's been such a long time that I forget sometimes, probably because it's not a very memorable story.
I came up with my username when I was six (or seven) years old when I was first joining a game called Roblox. Well, it stuck.
I use this username for just about everything now, even though I don't use that very first account anymore. As for the reason?
I button-mashed. I wanted a username with only a few syllables since I had just learned about those in school, and it sounded cool while having only six letters and no numbers (I thought numbers were stupid.)
And thus, Sozony was born. The only problem with this username is that no one knows how to pronounce it, and at this point neither do I, I've heard it pronounced so many different ways lmao.
