For the sake of the family porcelain kiln, she was forcibly married by that cold and mysterious man and became a prisoner. What he is obsessed with is just the "porcelain heart" mark on her shoulder blade that can unlock the secret realm of the lost official kiln. There are many traps in the secret realm. She pretends to obey, but leads him into fatal traps time and time again. Until the moment of life and death, he sacrificed his life to protect each other, and the oath of protection that had been hidden for hundreds of years emerged together with his twisted love. When the secret realm collapsed and before the eternal kiln fire, she used blood as glaze to bake the only "life porcelain" for him that could sustain his life. From then on, the fire revealed the true heart, and the broken porcelain condensed into new life. A bad relationship that began with robbery was finally tempered in the thousands of years of kiln fire into irreplaceable redemption.
