Hyun Woo decided that he would sneak up on Luka.. of course. Hyun Woo was a crew member for the show 'Alien Stage', a South Korean show that tells its stories through songs - perfectly. Hyuna, an actress, was his sister and they often hung out together, another actor he knew well was.. Luka. He was more careful with scaring Luka due to his heart disease, but he is stronger, strong enough to be able to sing, perform and act!! As they were both siblings, Hyun Woo and Hyuna were quite similar in appearance. Akin to his sister, he had tanned skin, grey eyes and brown hair. However, his hair had been cut much shorter than hers.

He did appear in the show a bit basically - but only his child actor did due to a scene in 'All-in' a song performed by Hyuna. Hyun Woo handles the lighting in scenes and often does it for Luka's mostly!!
