Yoo Il was cast as the lead role of the musical version of 'Secretly and Greatly,' which was published as a web-toon and for which a film remake was inspired, starring Kim Soo Hyun. The idol, who wowed everyone with his tap-dancing and stage presence for his musical debut 'Ro-Gi-Soo,' is drawing fans' anticipation as to how he will interpret the role of Won Ryu Han. 

Yoo Il relayed his thoughts on landing the lead role, saying, "'Secretly and Greatly' is great work which you can enjoy over and over again whether through the original web-toon or the movie remake. I've always thought that Won Ryu Han is a great character who possesses many cool characteristics so I'm thankful for being given the opportunity to portray him. It's an honor to stand on stage with veteran actors I admire and for a great piece of work; I'll practice hard until the very day the musical premieres. Please look forward to it."
