Focus on plot over character, creation of sequels only after initial success among main obstacles

"Sweet Home 3," starring Song Kang (Netflix) 

Korean series traditionally did not produce sequels, primarily due to Korea's production structure.

Unlike other countries, a series' intellectual property rights are distributed among production staff in a complex manner, which makes creating sequels challenging.

However, the landscape is changing.

International streaming platforms, especially Netflix, have begun introducing seasonal formats for Korean series. Following this trend, local cable channels such as tvN have also started adopting seasonal formats for their own series and it is quickly becoming a common practice for successful Korean series to produce a second season.
