According to the director, the underlying theme behind the series is ‘the intolerance of uncertainty that places people at their own hell.’ Yeon said, “The most important message that I wanted to deliver through this work is asking questions on humanity and what it means to be a human.” He further added, “The series begins as people encounter an unexplainable supernatural phenomenon. I wanted to wrap up the series by showing one of the most incomprehensible and unreasonable acts of will that a person can exhibit – self-sacrifice.”
He also answered why he only saved the newborn child of Bae Young Jae (Park Jung-min) and Song So Hyun (Won Jin Ah). “I have a child of my own, and I often become emotional when I watch kids on TV. You know how children can be made happy even with the smallest gifts. If a society fails to appreciate those children in our lives, then the society is ill and not sustainable for human welfare. By showing the newborn child at the end, I wanted to offer a surprising glimpse of hope that may lead them to a better world.”
