This Train Is a Little Too Terrifying

Train D444, also known as "Tribulation," is where some people are fated to meet their tribulation, whether because of their birth date and horoscope, the wrongs or regrets of a past life, the bad things they have done in this life, or...

Su Yang is the conductor of Train D444 and the one who controls humanity's tribulations.

Aboard the train, he sees the tribulations people are fated to face, as well as things invisible to everyone else.

At night, Su Yang controls humanity's fate. By day, he carries on his grandfather's legacy as a corpse cleaner.

Corpse cleaning is an ancient and mysterious profession. Whenever there's a death by jumping, a person hit by a train, a dismemberment... or any other violent crime that leaves a body in pieces, someone has to clean up the corpse and the scene.

Wait!!!

The red-clad woman with missing limbs he saw last night aboard Train D444... why does she look exactly like the woman her husband dismembered today??!!
