Commitments Printed on Paper

A library without windows, an administrator who has never seen a reader, a red book that turns its own pages. When you press your finger on the paper, the contract has taken effect - every time you turn a page, you will die in a parallel world, and in exchange, you will get all the memories of a book you have read in that world. The administrator stayed in solitude for seven years, until one day, he opened a book that did not belong to any shelf. He saw himself in the cafe, saw the woman clutching envelopes in the hospital corridor, and saw countless "me"s reaching their end on different paths of life. Every time he turns the page, he gains a piece of knowledge and carries an unfulfilled promise. But these commitments have a common name. The woman had been waiting for seven years, and someone was coming outside the door. And on the last page of the book, his own name was written. When the price of turning the page is no longer "another self", when the hand outside the door finally turns the doorknob - you will understand that the contract of the library is never to give knowledge, but to allow you to identify the version that truly belongs to you among countless endings. --- One sentence summary: An administrator trapped in an eternal library obtains knowledge by "killing himself in the parallel world" again and again, but in the process of turning the pages, he discovers that all the lost "Is" point to the same unfulfilled promise - and at this moment, the promise is standing outside the door. ---
