The Wangchuan Emergency Room

As memory-erasure technology became widespread, Zhou Xuan, an emergency physician at Wangchuan Memory Hospital, thought he had seen every price people were willing to pay to escape pain. Then Chen Wang was brought into the emergency room. The man had erased his memories of his daughter's death, and now, late at night, he kept repeating the same line of poetry: "Where we first met in this fleeting life, dreamlike as it was."

After the operation, a patch of blankness appeared in Chen Wang's mind where none should have been. It was too neat, as if someone had cut it out with a knife. As Zhou Xuan investigated, he found himself standing at the edge of a vast abyss.

Some pain seems as if you can go on living once you forget it. But it never truly disappears. It merely sinks into the depths, waiting for the moment when it returns, together with the part of yourself you threw away.
