Jin Mian is Su Moran's sister. She loves Gu Jinnian very much, but in the end she doesn't know what love is.
Gu Jinnian was very confused. He didn't know whether to choose Jin Mian or Su Moran. It was such hesitation that Jin Mian died [explained later
Su Moran hated Jin Mian very much. She had taken away everything that belonged to her since she was a child, so she wanted to be with Gu Jinnian and make her angry to death [...] But she didn't expect that Jin Mian's psychological endurance would be so weak.
In the end, Jin Mian died. He was pushed off the highway after an argument with Gu Jinnian [I don't know, maybe it will change, but he is dead anyway]. When Su Moran arrived, he found Jin Mian lying in a pool of blood, and Gu Jinnian's hands were covered with her sister's blood. Then I felt that I had gone too far.
Gu Jinnian was mentally stimulated and went to the doctor to forget about the past and stop thinking about the human life that was weighing on him, so he changed his name. Su Moran also blamed herself, but put all the responsibility on Gu Jinnian. He was the one to blame for her sister's death.
She wanted revenge and found Gu Jinnian [who was now known as Chu Zhan]. He buried everything in the past. He wanted to live a relaxed life, but he couldn't escape the self-blame, insomnia, panic, and confusion in his heart. At this time, Su Moran found out that he felt that he should be buried with his dead sister.
