Kang Baek-hyun went to buy tteokbokki (spicy rice cakes) for his sister when, suddenly, his body shrinks to 3 centimeters!
In fact, the entire human race has shrunk as well. Now the once harmless cats, sparrows, ants, and even robot cleaners become life-threatening. Mankind is in great chaos, but each person receives a gift to escape this crisis. Along with the ability to see their “status windows,” they are given mysterious powers.
In a world of despair, Baek-hyun must live on in order to protect his sister and save his friends.
