It tells a passionate and funny story about a father and son who have different opinions and travel back to the metaverse of the 1990s, working together to pursue their youthful dreams. On one side is the authoritative and stereotyped chaebol father Li Changhai, and on the other side is the rebellious and out-of-touch son Leo who wants to return to reality. The role change and identity exchange turn the former father and son into classmates and brothers in an instant, bringing nostalgic memories from an alternative perspective.
