Xu Ciyin was rumored to have jumped into the sea and died due to family reasons. Shen Huai saw with his own eyes that Xu Ciyin died in the sea in front of him.
Shen Huai didn't believe Xu Ciyin's death. In the end, he fell into a memory loop again and again, and each time he entered the memory rewrite ending with the remaining memories.
Finally, Xu Ciyin gained independent consciousness and Shen Huai had all the memories. Xu Ciyin kept talking about Shen Huai bringing out memories.
In the end, Xu Ciyin disappeared in front of Shen Huai, and Shen Huai also forgot about Xu Ciyin and everything about her.
Intention: His obsession traps him in memories, and the only way to escape is to forget him.
