Shu Wan had been Ji Sihan's lover for five years. She was diagnosed with heart failure and had not long to live. Ji Sihan's abandonment made her situation even worse. When she was about to resign, she suddenly learned that the returning Ning Wan was going to be engaged to Ji Sihan. She mistakenly thought that she was just Ning Wan's stand-in. Ji Sihan misunderstood Shu Wan again and again under Ning Wan's calculations, but he still couldn't let her go and helped her many times as Mr. Ye. He finally learned the truth despite all kinds of obstructions. All the misunderstandings were because of Ji's mother and Ning Wan. After revenge for Shu Wan, he chose to take his own life.
