Another suggestion is: A drama remake that is based of another drama. Example: Princess Hour Thai is based of Goong.
Yeah, but they're both actually adaptations of a manhwa!! So, my own suggestion for the 2021 Watch Challenge is to move "Adapted from..." to the regular section instead of the bonus section, since this is extremely easy to fulfil anyway -- I estimate more than 40% of all dramas are adapted from something anyway, be it a novel, a manga, a light novel, a webnovel, a manhua, a webtoon, a manhwa, a play, an anime, a video game, a legend/folklore/mythology, etc etc...
