Both are comedy-centric with slight romance stories written by the same screenwriter and starred by TOKIO members. Supporting characters in both dorama also share roughly similar quirky antics. It's just so funny to watch how they all interact.
The stories are different, but they give out the same vibe. They're both light-hearted and in both you have a delusional ''dorama in the dorama.'' The main character in both is also kind of the ''narrator'' of the stories, and doesn't get involved in the action personally, but acts as a catalyst for the plot.
Both dramas have a certain kind of humor that is enjoyable and have crazy, hysterical leads! Also, both have TOKIO members as the leads.
