Ock Joo Hyun will play the role of an exotic dancer, accused of being a German spy during World War I after her affair with a French intelligence officer, played by Seulong. 

Seulong raised anticipation for the musical, stating, "In a span of two and a half hours, the musical portrays reality. There is music, drama, love, war. Just so much content that it makes this musical even more incredible." 

'Musical Queen' Ock Joo Hyun shared a secret about being on stage, saying, "In reality my vision is very bad so on a daily basis I have to either wear lens or glasses, but when I perform for musicals I don't wear either. To be honest, not being able to see clearly is more helpful when I am performing, it is as if I can escape from my fears." 

'Mata Hari' marks Seulong's debut as a musical actor. He shared, "I asked Jo Kwon for a lot of advice when I first got the script, and he helped me recite my lines by taking on other roles." 

We wish Seulong the best of luck in his musical debut!
