They're both about secret family matters. Both very funny, bit longer than your typical 16 to 24 episodes, and a very good family show. But mostly alike on the secret family matter :) I love them both ^^
Both drama is about a heartwarming big family. But, the conflict in Kimcheed Radish Cubes is maybe a bit more complicated than Tokyo Bandwagon. Furthermore, Tokyo Bandwagon is shorter series than Kimcheed Radish Cubes.
