Music critic for V-chart of China YinYueTai: BaoBao（爆爆）, the Executive Chief Editor of the South Korea Division of Cool Music (Cool轻音乐), a famous Chinese magazine for K-pop & J-pop:
What was the Kim Jae Joong You’ve liked? A caring and sweet obba? A representative of flower pretty boys? Or the Hallyu star with ever progressing singing and acting skills? Each facet of Kim Jae Joong is in itself enough to turn you into his loyal fans. Yet, is the Kim Jae Joong who is now on the rocker track gonna make you as loyal as you’ve been? It’s an easy answer. You can see the answers to all the above questions from those who have always been supporting Kim JaeJoong as you see the title song of his first album , ‘Just Another Girl’ rose to number one in this month. The present Kim JaeJoong has more refined muscles and the complexion as polished by the passage of time. He’s not being as cautious as before to keep his image as an idol. He can hold a cigarette, release his mask, fling his hair and care less about from what angle he is photographed. With his music, he has entered the realm where his soul and body become one. And for us, we get a little closer to the real Kim JaeJoong. His identity as a rocker pulls us closer to him and makes us love him more.
