Actor Song Seung Hun made a solemn promise during his appearance on the latest episode of MBC's 'Entertainment Relay'.

During the program's interview of the main actors for the upcoming drama, 'When a Man Loves', the stars were questioned on what they were prepared to do for the new program's success.

Co-stars Shin Se Kyung and Choi Jung An promised to show off their abs while singing Choi Jung An's hit song, "Letter", if the drama reaches 30% in ratings.

Song Seung Hun attempted to one-up their goals, saying, "Then, I'll dress up as a girl and dance next to them."
