Actor Lee Kwang-soo, Zo In-sung, Sung Dong-il, Lee Sung-kyoung, and Tae Hang-ho gathered to celebrate the end of “Reply 1988.”

Lee and Zo posed with V-signs, while Tae and Lee gave a thumbs up for the picture. Sung was in the center holding a cake with a big grin on his face.

They had worked on the same drama “It’s Okay, That’s Love” in 2014, building their strong friendship.

In November, Zo offered a catering service for the staff of “Reply 1988” to encourage Sung.
