Emergency responder Zhou Ye always thought that everyone he saved was human.
That is, until the day he knew the silver-haired woman before him wasn't human and still chose to reach out and save her. A strange life-flame seal pierced his heart. As he lay dying, Su Fei, the Nine-Tailed Demon Lord, saved him with a passionate kiss, binding their lives together for good.
From then on, they couldn't be more than three hundred meters apart.
The haughty, icy, and notorious Nine-Tailed Demon Lord has no choice but to move into Zhou Ye's cramped home. One saves lives and heals the wounded, while the other can suppress a whole host of demons with a mere gesture. By day, they squabble over everyday necessities; by night, they face the demons and strange tales lurking in the city's shadows together.
A red flame that burns emotions, shadows that devour identities, demon seals awakening one after another... As a conspiracy capable of overturning the worlds of humans and demons gradually comes to light, Zhou Ye realizes that perhaps Su Fei didn't kiss him that day just to save his life.
At first, a contract kept them from parting.
Later, even after the contract disappeared, neither of them wanted to be the first to leave.
