Humanity decided to create a talking system to improve reality called WHtechs (Welcome Home Technology). Each robot, Julie, Eddie, Howdy, Barnaby, Poppy, Frank, and most importantly Wally (or W.DT02 or Wallace), holds an important role and features in technology and the human world.

Walden, owner of the Rainbow Factory and the CEO of the WHtechs, was known for his stern, cold-tempered, and tough attitude. But in reality, he deeply cared for the WHtechs robots. He was currently sitting at his desk, overlooking documents and sipping his black coffee.
