Death Rewind: I'll Wipe Every Vengeful Ghost from the World

My name is Ye Xiu. By the time you read this, I will already be dead. Yesterday, I swallowed an entire sheet of cephalosporin pills and downed half a dozen beers. I should be dead already. But this morning, I woke up again. Time had returned to before my suicide attempt. In the room lay another version of me, a knife buried in his chest. He grabbed me and screamed with pitch-black eyes: "Hurry up and kill yourself!" "Don't go to that place! It's full of ghosts!" "I barely managed to escape!" Before he could finish speaking, someone knocked on the door. Knock, knock, knock. The sound moved from the door to the window, then the ceiling, then the walls. At last, it burst inside my chest. My heart was crushed. When I woke again, I was lying in a garden beneath blinding sunlight. The roses bloomed with an eerie beauty, and the fountain tinkled softly. Six strangers were there with me. A white card laid out the rules: Find your seat before sunset. After nightfall, no matter what you hear, don't leave. At my seat, I found a black piano key. And I knew that the version of me who had warned me had escaped from a garden just like this one. Now it's my turn.
