The fictional alt idol group Sunny Side Up appears in both dramas. The group is more central to the plot in Dakara Watashi wa Oshimashita, but, indeed, the events in the first series are referenced in the second.
I AM NON is a ten-part documentary on the making of the film Get to the Punchline. It's hosted by Kurshita Honami who plays Kie in the film.
This is a scripted drama series by the same production company as the series and same director as the feature film. One of the panelists, Ito Kitaro, from Terrace House: Boys & Girls in the City and Terrace House: Aloha State plays a featured character, and there are three other Terrace House cameos as well. Every episode ends with the closing door sound effect used in all the other Terrace House series.
This is the third follow-up series produced by Netflix. It is set in Karuizawa, and is a return to form for the series.
This is the second series produced by Netflix. The house here is in Oahu, and, while the language was still Japanese, this series skewed a bit more towards conventional western reality TV drama which some fans preferred but most did not.
This is the first Netflix revival of the show. It too was set in Tokyo, and it is very similar in quality to BxGND, but did not last as long at 46 episodes.
This is the feature film sequel to the original series and provides a wrap up to the series. There are two versions of this film: the initial version is very similar to an extended episode of the TV series (but covering a much longer time span), and there is another version with the panel providing running commentary. Only the initial version has been given English subtitles by the fan group Costco Subs.
Both Sakuma Yui and Ito Sairi are in this 2017 morning drama as well. Sakuma has the much larger role here, but the two do have a few scenes together.
