We paid attention to the daily lives of youths living in the busy Seoul and overly competitive society. In particular, the MZ generation has gained a lot of information via online and has come to compare themselves with others easily. So youths try to invest their time in self-development even in their spare time as they are stimulated by the edited daily lives of social media influencers. Humans instinctively pursue the balance between work and rest, but young people in Seoul are putting off rest for the sake of developing life. Daily life without rest, which is directly related to health, harms young people, and the future of the city is becoming blurry.
