A strange commission from a mysterious wealthy businessman requires him to explore a broken childhood trauma. When Lin Mo dived into the dusty sea of memories, he was horrified to find that the little girl in his client's memory overlapped with the only afterimage in his mind. This is not only a business commission, but also a carefully designed reunion. On the island of memory, he must face the truth swallowed by the sea of forgetfulness.
