A normal story about an ordinary guy—nothing special in it except one thing: he loved a girl whom he lost in an instant. And all their plans, hopes for the future, collapsed in a moment. Who is to blame for this? Or did it happen by accident? No one can answer these questions. But the ordinary guy is quietly turning into a maniac—a psychopath obsessed with one idea: to take revenge. Revenge on people for their love and happiness.
