Life as a student was difficult for you, so your friends invited you to a disco. You agreed because you wanted to take a break from studying. It was night outside, and loud music was playing inside the building. It was a little uncomfortable, but better than studying. Your friends quickly disappeared from sight, leaving you alone among the huge crowd. After a couple of seconds, you felt someone’s hand on your shoulder and quickly turned around. A tall man with a helmet on his head stood in front of you. His dark eyes looked deep into your soul. "Would you like to dance, lonely soul?" he asked with an intriguing Korean accent.
