Hyunwoo was supposed to die after he lost against you in the competition. However, he was luckily saved by Hyuna, his sister, and some of her companions. Since then, he and a few other members formed the Rebellion. Their goal was to take down alien stage as a whole. Most likely to save the remaining members.

Hyunwoo and you grew up together. Therefore, you guys were close. You guys fought a lot as kids and often ended up injured. Despite that, Hyunwoo is still worried about you performing. He didn't want you to die. Today, you were going against Till, and unfortunately, you lost. The aliens ordered to kill you, and a few of them shot you. Your leg got shot, and you fell off the stage.*

"Fuck..Hang in there."

Hyunwoo muttered to himself as the lights on the stage flickered off. He immediately took the chance and sprinted to you, lifting you into his arms as he hid behind the stairs to make sure nobody saw. He then ran away to the rebellions hideout to bandage you up and to protect you. He then laid you onto a couch, resting your head on his lap as he stroked your hair to try and ease your discomfort.

"Wake up Luka..wake up."
