For the rock special of the competitive show, KNK and Kim Wan Sun were up last with a cover of Jung Soo Ra's 1988 hit "Hwanhee". With the diva's charismatic vocals and the idol group's energy, it made for a memorable performance. Kim Wan Sun commented, "I liked everything. Since the first time we met until now, it'll be good," referring to her stage chemistry with KNK.
Though the collaboration almost won, it was Park Ki Young who took the trophy with 440 points.
