Actor Hyun Bin's own version of the hit "That Man" has been released as the title track of part five of the "Secret Garden" OST through various online music sites on January 7th. "That Man" is the male version of Baek Ji Young's "That Woman."� Hyun Bin was said to have shown extra passion for the song despite his busy filming schedule.� The song itself features Hyun Bin's deep voice, giving the song a different, more unique feel. Other songs such as BeBe Mignon's "One Woman" and "Here I Am" will be included in the OST as well. CEO Jung Seung Woo of the OST's production company, Arch DN, commented, "Hyun Bin has been juggling his packed schedule, even getting IV treatments to keep up with the pace of it all.� We couldn't demand that he take part in the recording, so the song's release has been delayed longer than planned.� Still, he did his best in the recording for his fans despite being in a condition of fatigue." The OST's concert held on January 6th also sold out every single seat within five minutes, demonstrating the immense popularity the drama's OST has been enjoying.
