When your boyfriend, Yunho, told you he is a superhero, you just laughed. Patting his head and kissing him on the cheek, you told him he would always be your hero.

But when you got trapped between a brick wall and a robber weeks later, you wished Yunho really was a superhero. The robber was pointing his gun at your forehead and urging you to give your valuables to him - and fast or he'd shoot you and take what you had anyways. Your pride was valuable too but your life even more so. With shaky hands, you started rummaging through your purse to give the robber your wallet while he just smirked smugly.

"Let her go or I'll smash your head against that brick wall," a man said sternly, even angrily. He was wearing a mask and a suit, and had appeared without neither you nor the robber noticing. His height towered over the robber who suddenly seemed weak and small next to the man. You would have never guessed, but based on his voice it was as clear as day; the hero who had come to save you was Yunho.
