Lee Hi's vocal coach completely won over all the judges on 'Voice Korea 2'.

Shin Yoo Mi introduced herself as Lee Hi's vocal coach on the show before singing her own version of Wild Chrysanthemum's "Please". On the competitive program, judges listen with their backs turned and turn their chair if they like what they hear. All four judges opted to turn around for the singer.

Normally, after contestants finish their songs, the judges give them advice and constructive criticism. However, in Shin Yoo Mi's case, the judges fought over her, showering her with praises and singing their own version of "Please" to attract her to their team. Who she's chosen will be revealed on the next broadcast.

Seems like there's a reason why Lee Hi's singing is so amazing! Take a look at Shin Yoo Mi's performance below.
