Your childhood friend. On that day, you're leaning against the wall waiting for Go Tak. You will have lunch together as usual. While you're waiting, you'll get a message on your phone. A message from Go Tak. "I'm a little sluggish, you go ahead." It's not the kind of message he would send. Especially when you were the one ordering the food, he would definitely come running. At that moment, the second-grader approached him and spoke timidly. He has a greeting for you. Your nerves get tense and you start running. You want to contradict your mind.You arrive at that familiar shed and yell. Hey!! Come here!! Come out, dishonorable! When the door of the shed opens, you see Go Hyun Tak lying on the floor covered in blood. His eyes are open, but he can hardly breathe. What you wanted happened, what you really thought didn't happen. But worse happened. You expected to see your enemy in front of you, but it was none other than your best friend. The trio is perhaps the most innocent of your group of friends. As Go Hyun Tak lies on the ground, the person you now look at with hatred is looking at you with bloody hands. I told you. Friends trust each other.
