I have a suggestion. Would it be possible to add Cameo to the list of roles given? In many of our dramas and movies, it's more accurate to label an actor as a cameo appearance rather than as a guest role since they only appear for a brief moment. Cameos are generally not credited because of their brevity, or a perceived mismatch between the celebrity's stature and the film or television series in which they are appearing. Many are acknowledgments of an actor's contribution to an earlier work, as in the case of many film adaptations of television series, or of remakes of earlier films. Others honor actors for their work or relationships with fellow stars or directors.
A cameo role is one where a celebrity makes an appearance, often a one-scene appearance with no connection to the story or plot. (Source: https://www.facebook.com/vetaglobal/posts/the-difference-between-a-cameo-and-a-guest-rolebollywood-movie-buffs-know-that-w/252348381557561/)
An example to change would be Kim Seul Gi's appearance in Love in the Moonlight. She comes in in the last episode as a eunuch where she appears for about 2 seconds. Her most recent role at that time was as a eunuch in Splash Splash Love.
An excerpt from Wikipedia :
A cameo role or cameo appearance (/ˈkæmioʊ/; often shortened to just cameo) is a brief appearance or voice part of a well known person in a work of the performing arts. These roles are generally small, many of them non-speaking ones, and are commonly either appearances in a work in which they hold some special significance (such as actors from an original movie appearing in its remake) or renowned people making uncredited appearances. Short appearances by celebrities, film directors, politicians, athletes or musicians are common. A crew member of the movie or show playing a minor role can be referred to as a cameo as well, such as Stan Lee's frequently performed cameos : )
Concept
Originally (1920s) "cameo role" meant "a small character part that stands out from the other minor parts". The Oxford English Dictionary connects this with the meaning "a short literary sketch or portrait", which is based on the literal meaning of "cameo", a miniature carving on a gemstone.
Possibly the best-known series of cameos was by Stan Lee, who made very brief appearances in most of his films.
