Comedy series centered around the Young-gu character played by Shim Hyung-rae. Originally as a spin-off of the character from A Journey (1986), the movies focused more on the comedic aspects of Shim Hyung-rae's persona.
Moon Chul, Hak-gyu, and Young-ok are students in the sixth year of the National School of Life and Guidance. They have excellent academic performance, but above all, they are children who have unrighteousness and have a lingering suspicion that they cannot endure. But sometimes it's a valiant three-gunner who turns around with a miscivous joke.
