On May 5, MBC aired a pilot episode of their new variety show, Secret Variety Training Institute, with a long list of idol guests. The aim of the program is for mentors HaHa and Noh Hong Chul to train idol guests to become variety all-stars.
During the episode, the guests showcased an epic dance-off for different categories of dances such as cute, tough, sexy, and healthy. The first category was cute, and BTOBs Yook Sungjae battled Akdong Musicians Lee Soo Hyun. Although both of them had some adorable moves, Yook Sungjae gave the win to Lee Soo Hyun.
