Our Gap-soon

Our Gap-soon is a 2016–2017 South Korean television series starring Kim So-eun and Song Jae-rim. This is the first time that a virtual couple from MBC's We Got Married co-stars as main cast in a serial drama on a national Korean television network. It aired on SBS every Saturdays to Sundays at 20:45 (KST) from August 27 to October 30, 2016, and then 2 episodes every Saturday from November 5, 2016 to April 8, 2017. This change generated a rating increase that led to an 11-episode extension, making the series end with 61 episodes.
