This is from Entertainment Weekly, I’ve watched last night.
Placed 4th is lee seunggi and hyoji couple from Brilliant Legacy
Placed 3rd is byeonghun and Taehui
Placed 2nd is Bae Yongjun his Winter Sonata couple
I’ve forgotten what is the name of the couple that placed 1st. From a glanced, i looked like Uhm Taewoong.
