Lin Wan has a rare time perception disorder - her brain will jump uncontrollably to the future and see fragments of what will happen to him.
Chen Yu has an inexplicable tendency to synchronize memories - he always sees a girl crying in different scenes in his dreams. When he wakes up, his chest feels tight, as if he has lost someone important.
They were high school classmates.
She saw that he would be hit by a car on a rainy day, that he would lose opportunities because of her words, and that he would lie in the hospital with a smile and say, "It's good that she's fine."
So she pushed him away again and again - being cold, avoiding, and saying hurtful things. He didn't understand why, but after waking up from every dream, he would still put breakfast on her table, pass tissues when she cried, and run to her classroom door before it rained.
Every "bad future" she foresees comes about because she tries to avoid it.
Every "her sadness" he dreamed of was a picture of her crying alone in a parallel branch because she missed him.
They all love her to the core.
But one ran away because of foreknowledge, and the other chased because of a belated dream - always half a step away.
In the end, she chose a cure: forget him, to eliminate all future memories of his injury.
He chose to let go: let her go to a world without him and live well.
Years later, they met on a street corner.
She smiled at him, eyes clear and no longer afraid.
He didn't recognize her, but the tears fell.
Intention: When love becomes the only "harbinger of disaster" for each other, letting go is not betrayal, but the final protection.
