Onmyoji Juedu, who understands yin and yang, but does not understand human emotions. He was born as a walking piece of "human-shaped black ice" with a Yin fate. He has been with monsters and monsters since childhood, and regards warmth as a fearful path.
Until he met Wen Yu'an, a young man who seemed to have used the wrong life script. He is never right in his mouth, but he can accurately hit the weak spot of Juidu's stomach and heart with a bowl of hot Yangchun noodles.
When Wen Yu'an saw Jue Du catching ghosts for the first time, his eyes widened in shock.
When Juidu is in danger, Wen Yu'an will be the first to rush out and protect Juidu with his own body.
However, as one case after another comes to light, all the clues point to Wen Yu'an - the only source of warmth that Juidu is willing to approach, which seems to hide a shocking secret that even he himself doesn't know...
Fate knocks on the door. Is this his salvation or the final disaster in his life?
