Lin Qi forgot about Su Wan.
On the eve of the college entrance examination, he went to an appointment to confess his love, but there was a car accident on the road. When he wakes up, he remembers everyone except her. What he also forgot was his childhood sweetheart for seventeen years, the three hours she waited for him, and the yellowed medical certificate he pressed in the letter.
Reunion after seven years. She is a cardiac surgeon and he is someone else's fiancé.
He politely called her "Doctor Su", polite and distant, like a stranger.
Until he found the iron box in the old house. There was an unsent letter in the box, with a medical certificate tucked inside. His handwriting is sloppy and forceful——
"If she needs a heart, I can donate it."
He finally remembered everything, stood on the river embankment and said to her: "I remembered."
But Su Wan just took a step back.
"It's late."
It took her seven years to learn never to look back. It took him seven years to discover - it turns out that I forgot you, but I never forgot to love you.
Concept: Memory will be absent, but love will not
