When she was nineteen years old, Lin Wan got a key that could go back to the past. She thought this was the second chance given to her by fate, so she went back to the past again and again to win back those who left, make up for the wrong words she said, restart broken relationships, and try to save those who were destined to be lost.
But she soon discovered that the key was never free. Every time she changes the past, the world forgets her a little. Friends forget her habits, her father cannot remember their shared childhood, and her image in the photo becomes blurry little by little... Until one day, everyone will completely forget that Lin Wan ever existed - except Shen Yan. No matter how many times time was reset, he always remembered her. He remembered what she liked and what she was afraid of, the first time they fell in love, and the rain that had not yet happened that would take away Lin Wan's life.
Lin Wan originally thought that this was the first time they tried to change the ending. Until she discovered that Shen Yan had saved her many times in countless abandoned timelines. They fell in love again and again and lost each other again and again.
And this time, time leaves them with only one last choice: If the only way to save you is to make you forget me forever, will you love me again?
Purpose: The work explores the boundaries of love, memory and choice. True love is not about deciding the fate of the other person, nor is it obsessed with rewriting all regrets. It is about still respecting each other's choices and cherishing the real encounter at the moment when you know that you may be lost, forgotten or even separated. Time will take away memories, but it cannot deny the feelings and companionship that once existed.
