Look, this is my drawing! I have a large black circle here, and in the middle is a red stripe, like a bridge or a door. It divides the circle into two halves, like two pieces of pie. I imagine this red stripe as a barrier that says, "Stop, you can't go any further!" But if you look at it childishly, it looks like a superhero's red belt, holding the circle together so it doesn't fall apart. The top half of the circle is like a hat, and the bottom half is like a plate. And the red stripe between them is like they're talking to each other and sharing secrets.
I drew it this way on purpose to make it look like a sign, but in my imagination, it's not just a sign, but a magic circle guarding the entrance to a fairytale town. If you want to get through, you need to guess the password, and the red stripe decides whether to let you in or not!
