Yan Feng and Ye Yun, who love each other deeply, were originally a couple that everyone envied, but fate struck them unexpectedly - Ye Yun was diagnosed with leukemia during a physical examination. Unwilling to drag down his beloved, he cruelly fabricated lies about their breakup, and even asked his junior high school classmate Yang Fan to pretend to be a couple, just to make Yan Feng give up and leave completely.
She thought this was the most gentle fulfillment, but unexpectedly it led to the most tragic tragedy.
Yan Feng, who was kept in the dark, lost control because of love and hatred, and paranoidly embarked on the road of revenge: he hired the killer Nightingale to get rid of Yang Fan. Later, in order to cover up others' eyes, he killed Nightingale and silenced her. Little did he know that Nightingale was actually the lover of his sister Yan Xue. In order to cover up the crime, Yan Feng cruelly deceived his sister and placed all the blame on Ye Yun.
Yan Xue came to confront Yan Feng in grief and anger. Ye Yun couldn't bear to bury the truth and took out the ironclad evidence of Yan Feng's murder for surveillance. The truth pierced everything like a sharp knife. Yan Xue had an emotional breakdown. She couldn't bear the blow and fainted. After waking up, she became crazy and crazy.
Yan Feng, who had been betrayed and separated from her relatives, poured all her resentment towards Ye Yun, constantly irritating her with vicious words, and even angered her to death while she was seriously ill with his own hands. It wasn't until he accidentally discovered Ye Yun's diary that the deep love, illness and despair hidden under the indifference and betrayal flooded him like a tide.
Love turns into hate, good deeds turn into calamity, one wrong thought, and everything is lost. When the truth is revealed, there is only endless regret, but the person who tried his best to protect him will never come back...
