With the thought of a substitute marriage, she became a prisoner of his hatred; a misrecognition led to a bone-crushing sadomasochism.
In order to save the family, Xu Nian married Lu Chenyu, a business tycoon, in place of his sister. On their wedding night, he warned coldly: "How does a scapegoat deserve respect?" From then on, endless humiliation and torture became her daily routine. She endured it silently because she hid a deep secret - she was the girl Lu Chenyu was looking for so hard back then.
When Lu Chenyu's attempt to protect Bai Yueguang in her heart caused Xu Nian to lose their child, she finally gave up and left behind a divorce agreement and a painting called "The Prison I Always Loved", which disappeared without a trace.
It wasn't until she was reborn with light and returned as a famous painter that Lu Chenyu was shocked to realize the truth - he hated the wrong person and loved the wrong person. He put aside all his pride and embarked on the difficult road of chasing his wife, spending the rest of his life atonement.
"Xu Nian, let me love you until the end of my life."
"Lu Chenyu, we have long been reconciled."
This is a sadomasochism that begins with misunderstanding, a deep love story about redemption and growth. See how they finally gained a new life in that cage called love, after their bones were eroded and their hearts were burned.
