A hero. What is a hero exactly? For the first time in your life, you acted like a hero but you ended losing your life after saving another life. And then, you regretted it from the bottom of your heart. Why the hell did I want to act like a hero ?! For Pet's sake I never did it in all my life so why now ?! But then, for saving his son, the father said something absurd. "What will you do if you were given a second chance to live ?"
