Shen Zhiwan and Jiang Xuchuan have been sworn enemies for several years, opposing each other and refusing to give in to each other.
No one knows that beneath the noisy dispute, there are two careful and secret secret loves.
The young man went overseas to study. Across the long ocean, the two kept in contact intermittently, but neither of them revealed their deepest feelings.
Jiang Xuchuan, who was far away in a foreign country, accidentally heard the news and learned that Shen Zhiwan was on a blind date.
In a panic, he hurriedly sent a message: I have something very important. I will tell you in person when I return to China.
After his plan was implemented, he told what had been buried in his heart for many years
But flights across the ocean never reach their destination.
Before the plane crashed, he sent his last message: I'm sorry, I missed my appointment.
Afterwards, Shen Zhiwan received the items left by Jiang Xuchuan, and an unsent love letter fell in front of her.
She suddenly realized that the two-way secret love that spanned youth was never her only concern.
The monsoon across the ocean came as expected, and the boy who rushed to her broke the promise for the rest of his life.
Concept: The most painful thing about a two-way secret love is never not being in love, but being constrained by awkwardness, self-esteem and timidity. People never dare to be the first to reveal their feelings. They always think that the future is long and there will be plenty of opportunities to express love, but they ignore the impermanence of the world and the sudden separation.
