Episode 20 recap: Shan Yu was killed by Zheng Zhe ten years ago.

Ten years later, Zheng Zhe, unwilling to see Shan Yu and Min Ying happy together, was plagued by jealousy from beginning to end. He always believed that the one who should have fallen into the abyss was Shan Yu, not him. So he called the Zheng Zhe from ten years ago, revealed his identity, and shared many secrets that only Zheng Zhe knew. Zheng Zhe believed him and, according to his own request from ten years later, went to kill Shan Yu. At that time, Shan Yu happened to be at the doorstep of Min Ying's house. Zheng Zhe drove a van and rushed over, directly knocking Shan Yu away.

Yin Xun thought of the candles lit by Shan Yu somewhere and called Min Ying while rushing to find Shan Yu himself, fearing that Shan Yu might encounter another accident like last time. However, when Yin Xun arrived at the car, he didn't see anyone inside. Calling Shan Yu still yielded no response. At that moment, Shan Yu was still in the past, where heavy rain poured from the sky. Shan Yu woke up from the rain, looked at his phone, which was shattered from the impact and completely unable to contact the outside world. He couldn't even manage to struggle to stand up, and his cries for help were feeble. Weak and lying in the rainwater, Shan Yu remained helpless.

Yin Xun worried that Shan Yu might once again be persecuted by Zheng Zhe. Min Ying hurriedly came to confront Zheng Zhe and questioned him about what he did to Shan Yu ten years ago. Zheng Zhe, on the other hand, remained calm and admitted that he killed Shan Yu.
