A five-year-old boy suddenly remembers his past life as a thirty-three-year-old game developer wannabe.

But this is not the future.

It is 1988, in a Korea that was never divided, in a world where history took a different path and the game industry is still in its infancy. Armed with memories of modern games, future design trends, and one lifetime’s worth of regret, Kim Insu decides to do what he failed to do before.

He will make games.

The problem? He is five. His tools are primitive, the internet does not exist, and even drawing decent graphics is a battle. But with a computer-loving father, a supportive mother, and a talented older girl who dreams of becoming a manhwa artist, Insu begins building his first RPG one line of code at a time.

Before legendary genres are born, before the industry finds its giants, one child sets out to become the pioneer who changes gaming history.
