During the 5th episode of 'The Butlers', the cast of the show ate together at their teacher's house. However, they were still feeling a bit peckish and so, decided to put 2 pieces of meat on the line as to who can steal the heart of the teacher's wife.�

As soon as Lee Seung Gi proposed the idea, Sungjae immediately got to work and started singing "Missing You". The rest of the cast was taken back for a brief moment and just watched Sungjae. Lee Seung Gi could not idly just watch and he himself started to sing passionately with even his eyes closed.
