The Years I Was a Ghost Waiter

The moment I woke up, I found myself in the underworld, and was told by the man in front of me that I would follow him and work as a waiter in his hotel, also known as the legendary waiter. I was ignorant and agreed, and I have been doing this for nearly ten thousand years. During these ten thousand years, as a waiter in the only hotel in the underworld, I encountered many strange things, including anecdotes about the rich man's family, secrets about the underworld, mysterious masters causing trouble in the underworld, and so on.
