Black Coffin***

I worked overtime until late that night, and the elevator suddenly lost control and dropped all the way to the -18th floor. The door opens to a corridor, a bus, and seven strangers. The voice said: Welcome to the old black coffin house. During the seven-day vigil, do not look directly at the coffin. There is one among you who is not a human being. Find him within seven days, or be killed by him. I thought it was just a bad dream. Until the first person to escape had his head screwed off and his face was covered with a black handprint. Until I saw the person lying in the coffin, it was myself. Until I found out, I was already dead. But I'm still alive. One door, another door. Mental Hospital, Midnight Live, Deep Sea Train, Mirror Apartment... Every time you clear a level, you get a fragment. Collect seven of them to open the door and find your mother who disappeared twenty years ago. But the fragments will make me forget the most important people. I forgot her name. Forget about her face. Forgot why she left me. All I remember is that she was waiting for me behind the door. But when I finally gathered the seven fragments and pushed open the door—— The person standing in the door is myself. The voice came from all directions: "Welcome to Black Coffin Games." "Now that you're here, it means you're dead." Silence, a twenty-eight-year-old ordinary programmer, was thus involved in this death game.
