At Midnight on New Year's Eve, I'm the Only One Left in the World

After a deep sleep on New Year's Eve, I woke up and the world suddenly changed. 1.4 Billion people have disappeared inexplicably, prosperous cities have become empty cities, and I am the only one left in the world. All communications were interrupted, and there was no trace of relatives, friends, or neighbors. Checking the surveillance, I saw a horrifying scene of my parents standing silently beside the bed late at night, leaving words that chilled my bones, and then took my sister and left decisively. My girlfriend hides a deep secret and deliberately avoids it when she is young. Everyone around her has deliberately concealed it. Endless fear, anger and despair enveloped me, and I thought I had been abandoned by the world. And in the dead silence of the empty city, there is a chilling secret truth hidden. I am trapped in this strange and lonely world, enduring everything alone.
