In the near future where memories can be read, repaired or even deleted, Lin Mo, a top memory restorer, makes a living by sneaking into the depths of other people's consciousness to repair incomplete memories. He can cure everyone's heartache, but he can't piece together the crucial blank of his childhood. A mysterious commission drew him into the whirlpool: Client Su Qing requested to delete a seemingly ordinary memory of a broken love, but at the core of the memory there was a strange "crimson hourglass" hidden. When Lin Mo sneaked into the foggy memory corridor, he discovered that it was not only the client's secret, but also the only route to his own island of memory, and beyond the island was a sea of oblivion that could swallow everything.
