"Obsessed" Actor On Joo Wan Used to Be Yunho's Dance Teacher?

“Obsessed” (aka “Human Addiction”) actor On Joo Wan recently revealed his past as a dance teacher for SM on the May 7 episode of MBC’s “Radio Star,” which also featured “Obsessed” cast members Song Seung Hun, Jo Yeo Jung, and director Kim Dae Woo.

On the episode, Song Seung Hun mentioned On Joo Wan’s dancing skills: “He says he used to be U-Know Yunho’s dance teacher.” Embarrassed from seeing the hosts’ surprised expressions, On Joo Wan explained that he taught dance at SM for a bit.

Of course the hosts couldn’t let this go without seeing the former dancer in action, so upon request, actor On Joo Wan sang a part of Vibe’s “Are You Crazy” and then got down, channeling his old dancer self.
