They met a woman who kept evil spirits confined with her own life, all for a fleeting moment of love; a mother who loved her son more than life itself, yet ultimately killed her own child with her own hands; and an old man who guarded a promise until death, unaware that he was still lost in an endless wait...
There is so much in this world that remains beyond our reach. Together, he and she saw what others longed for, and glimpsed what she herself longed for. Then she became what he could never have, while what she longed for had nothing to do with him.
She said, "You think you like me, don't you? But scientifically speaking, that's just your delusion."
This is the story of an otherworldly woman with overwhelming strength, a cool exterior, and a fragile heart, who meets an ordinary human. He seems harmless, but can slaughter his way through any fight with martial skill and resolve matters without bloodshed through his words. He makes our hot-tempered, moody heroine drop straight out of danger mode.
