On Friday, BoA sang her seventh album title song "Only One" live on KBS 2TV "Music Bank."

BoA managed to dance her choreography perfectly with her long, straight hair waving. Also, she also showed off perfect dance duet with Eunhyuk when she danced for the highlight part of the dance.

BoA proved herself the perfect role model for younger singers by showing perfect live with hard choreography.

On the other hand, "Only One" is a medium tempo R&B song that BoA wrote by herself, with a grand orchestration.
