[talk] The power of I-KNOW was palpable after seeing Yunho's new album on stage.

I saw Yunho's 'I-KNOW' performance on Music Bank and I immediately understood why it ranked #1 on the Oricon chart in Japan.
I was a little curious because I heard that this album has a fake and documentary concept.

The title song Stretch has a clean performance and is still crazy energetic.

Body Language was fun to watch because the styles were completely different.
