Welcome, Is This Your First Time in the Afterlife?

Oh Sora, a bright 21-year-old college student majoring in dance, boards a luxurious cruise ship anchored on the Han River, unaware that she's in a coma. Everything is free on the cruise except for what's not allowed, so she enjoys drinking and having fun all night. However, when she wakes up, she finds herself in disbelief, "Wait, is this the underworld?"

Amidst the chaos caused by the major accident of a living person entering the underworld, the examination hall is turned upside down. In the midst of this, a savior steps in to resolve the situation. However, the sharply handsome underworld civil servant who is about to sober up turns out to be quite grumpy.

Anyway, the situation could be resolved once they return to the living world, but strangely, the data of Sora's life stored in the underworld has been deleted in the blink of an eye. All that remains is her name and a few scant pieces of information. Furthermore, if Sora fails to find her body within the grace period of 49 days, she will be classified as a lost soul and forcibly admitted to the underworld...!
