Im Soo-hyang, Nanchang Hee, and Kim Dong-wook. cast members are bearing the damage caused by the superposition formation of the broadcasting company. Two Spin-off tvN new Mon-Tue drama 'beneficial fraud' starring Kim Dong-wook and KBS 2TV new Mon-Tue drama 'How did you meet' are broadcasted at the same time. Both Spin-offs started broadcasting in May. Although there is a difference in the time zone, due to the nature of the drama that is broadcasted for more than one hour, it is inevitable that Kim Dong-wook, the main character of both Spin-offs, appears superposition for about four weeks. Kim Dong-wook only wrote a stigma called 'superposition appearance' in the form without consideration of broadcasting station. 'superposition' means that celebrity cast members appear simultaneously on a number of programs broadcasted during the same time period. In the past, when competition for viewership was fierce, it was considered an unwritten rule to avoid "superposition appearances" among cast members. However, as the production environment has changed recently, there has been a situation in which 'superposition appearances' are made regardless of cast members' intentions. There is an increasing number of cases in which the drama is taken as a pre-production, the formation is decided afterwards, and the 'superposition formation' is different from the one when the appearance is decided. Actor Im Soo-hyang also suffered the same damage. SBS Mon-Tue drama "We Are From Today" starring Im Soo-hyang in May last year and MBC gilt drama "Doctor Royer" were broadcast at the same time. As a result, Im Soo-hyang crossed Fridays, Saturdays, Mondays and Tuesdays, screening genres in "Dr. Royer" and romantic comedies in "We Are From Today". 'We started filming from today', but there could be confusion for viewers, so Im Soo-hyang had to face the criticism of 'superposition Actor' unintentionally. In recent years, cast members have suffered damage due to 'superposition formation' in entertainment. It is Nanchang Hee who got off at MBC entertainment program 'What do you do when you play?' Nanchang Hee was appearing as a member of the pagoda in the Tintin Entertainment Project, which was held at 'What are you doing when you play?' However, the JTBC entertainment program 'Korean food', which started broadcasting, was formed at a similar time and got off the project ahead of the recording of the pagoda. Moreover, the pagoda project was what Yoo Jae-seok had been doing with his best juniors for three years. Nanchang Hee suffered for three years together, but due to the unspoken nature of the broadcasting company, he left the pagoda one morning. The remaining members of the pagoda also had to work harder to fill the vacancy by losing one member. In the meantime, Kim Dong-wook has been damaged. It is doubtful whether the situation in which three major cast members of each content Spin-off have been directly or indirectly damaged in a year is reasonable. Even though cast members are trying to avoid superposition by taking disadvantages like Nanchang Hee and getting off, is there any problem of broadcasting station trying to avoid it? Although formation is a channel-specific authority, it is hard to erase the impression of pushing without consideration and anxiety. In the pre-production-oriented current broadcasting system, the existence that induces 'superposition' is the broadcasting companies that are responsible for the formation, not some drama supporting Actors who have to survive prolificly. At this point, 'superposition formation' rather than 'superposition appearance' is not right. It is cast member and viewer who confuse image consumption and city hall. It is even harmful to broadcasters who decided to form first. SBS, who formed 'We Are From Today', was the perpetrator to MBC who first formed 'Dr. Royer', and KBS, who formed 'How did you meet', told tvN, who was in 'The Speech' JTBC, who introduced 'What do you do when you play? It was like throwing a stone at MBC's MBC. In the end, all the members have to take the damage of the schedule. Is there any solution? The reality that the cause provider and the victim are separate is sad. D.B., MBC.
