Cheolsu, a textbook-perfect character from old Korean elementary school problems, finds himself struggling in modern society. Recently dumped by his girlfriend, Saemi, without understanding why, Cheolsu turns to Dr. Kim Leonardo, a psychiatrist who claims that Cheolsu’s adherence to social stereotypes as a Korean man is holding him back.
Desperate to reunite with Saemi, Cheolsu embarks on a journey of radical self-discovery, taking him to the satellite city in search of answers. In the past, Cheolsu, Younghee, and Baduk were symbolic characters featured in school exercises, solving simple problems like sharing apples, representing socially accepted ideals of Korea.
However, as Cheolsu grows up and tries to conform to societal expectations, he begins to question whether blindly following prescribed rules truly leads to happiness. He explores his poignant and often humorous search for identity and purpose, delving into what it means to live authentically in a world that values conformity. Through his journey, the film challenges the stereotypes and norms that shape our understanding of success and self-worth.
