work environment, along with whether to sign contracts with domestic and foreign OTT companies such as Netflix have served as variables. For example, Kingdom had a budget of ₩2 billion per episode, while ₩3 billion were spent on each episode of Sweet Home. Often, production companies overrun their budgets and cannot pay salaries. In 2012, actors held a demonstration in front of the headquarters of KBS, expressing their concerns. Actors are usually paid after the last episode is aired. In series made by smaller production companies, there have been cases where the companies went bankrupt and could not pay their actors and crew, while the channel denied all responsibility, claiming all liability was with the bankrupt production firm. Producer Kim Jong-hak spent ₩10 billion on Faith, which was considered a commercial failure, resulting in the inability of Kim to pay crew salaries and other overheads. Kim, who had produced iconic dramas such as Eyes of Dawn and Sandglass, committed suicide after he was accused of embezzlement. The biggest stars may earn more than ₩200 million per episode, with Kim Soo-hyun, the lead of hit dramas Moon Embracing the Sun (2012), My Love from the Star (2013) and It's Okay to Not Be Okay (2020) reportedly receiving ₩500 million per episode for One Ordinary Day in 2021. Filmmaking process As producing a series involves high expenses, production companies seek to shoot the episodes in the shortest time possible. In contrast to practices elsewhere, the first four episodes of Korean series are usually shot in advance, but the rest are shot continuously as the series is being aired. Scripts are not finished in advance, and may change according to viewer feedback and viewership ratings, where popular characters receive increased screen time and plotlines are changed to match audience expectations. These changes may occur a few hours before daily shooting, and the crew might receive only a few ready pages. The production usually works with three camera crews, who work in a rotating manner to speed up filming. Because of unregulated script changes and tight shooting schedules, actors are almost continuously on standby, and have no time to leave the set or sleep properly. The Korean media have a separate word to describe irregular, short sleeps that actors resort to, in often uncomfortable positions, or within the set: jjok-jam (쪽잠), or "side-sleeping". Dramas usually air on two days every week, with following episodes
