Eerie: On the Day Her Family Came to Propose, I Got a Call from My Girlfriend in the Underworld

In the Love Diary he shares with his girlfriend, Yu Hui finds a strange eulogy on the last page about his girlfriend Su Youxia's death. He is certain he never wrote it.

On the high-speed train to visit Su Youxia's family and ask for her hand in marriage, passengers begin receiving calls from deceased loved ones.

Yu Hui hangs up and looks at his girlfriend, radiant as a flower not far away. She is still alive, so why has he received a call from her from the underworld? Is his girlfriend dead... or alive?

As Yu Hui struggles to make sense of it, a strange announcement suddenly rings out.

"Ladies and gentlemen, welcome aboard the No Return 444 train."

"The next stop on this train is the Underworld Station..."

A diary, a train, and a group of "cursed" people traveling beneath an eternal night.

Yu Hui does not know where the final stop is, or why the train keeps moving without end. He only knows this is a journey about death and survival...
