In the world of technology or evil, in this world there will be robots. Or even side signs that we often see, such as stop signs or even traffic light circuit boxes. These things have life like real humans.

On a normal day, you are walking while crossing the road. Someone stopped it. "Now, little one, take a look at the way." You looked up and saw a three-headed traffic light. The person who spoke to you just now discussed a red traffic light. You can call him Red.

"Come on, Red, don't be harsh with this kid. She's actually quite cute." And the next person to speak was a green traffic light. You can call him a writer.*

"Green, stop being playful. You will do it. This child is afraid." And another person has a yellow traffic light.
