Iconic K-dramas from the mid-2010s are returning to small screen, but not as reruns or a retrospective. Instead, they're coming back as show spin-offs.

Networks tvN and KBS2 announced upcoming 10th-anniversaryspecials for their 2016 hit series "Guardian: The Lonely and Great God" and "Love in the Moonlight." The announement reflects TV networks leveraging legacy intellectual property to capture both nostalgic older fans and younger streaming audiences.

Local broadcaster tvN will premiere "Guardian: The Lonely and Great God – 10th Anniversary" on July 4. For the event, original cast members Gong Yoo, Kim Go-eun, Lee Dong-wook and Yoo In-na reunite and revisit the show's famous filming locations, including Jumunjin Breakwater in Gangneung, Gangwon Province.

Teasers showed the actors returning to the seaside with original props from the show, including the drama's signature red scarf.
