Yin Suxi fell in love with Chi Jibai when he was seventeen years old.
He is a genius known to the whole school, the one who will build spaceships in the future.
She said she wanted to dive into the Mariana Trench. He said he was waiting for her to come back.
Three months before the college entrance examination, she signed all the consent forms by herself. On the day after the college entrance examination, she left a note in the hole in his desk that read: "I never liked you."
Ten years later, the national deep space-deep sea linkage scientific research project was launched. As the chief pilot of deep-sea exploration, the moment she opened the conference room door, the man sitting on the track design seat raised his head and called her: "Dr. Yin." His tone was calm, as if he had never known her before.
They fell in love again. Like ten years ago, but deeper and heavier than ten years ago.
But the deep sea gave her everything she wanted - silence, darkness, and free sinking. It also gave her an end point that she could never reverse. She slowly wrote fifty-two suicide notes, one per week, leaving him with all the sunsets for the rest of his life.
After her death, Chi Jibai suffered from psychogenic pure alexia and spent three years re-understanding the fifty-two letters word by word. The last line of the last letter read: "Chi Jibai, I'll wait for you below. But don't come in a hurry."
There he went. Taking all her suicide notes and a whale he had been drawing for half his life, he sank into her trench.
These are two people on opposite sides of an abyss calling each other for help.
One dived too deep, the other waited too long.
Finally one day, they met in the deepest part.
Concept: Some love is the echo of the abyss to the abyss. The moment you sink, the echo can hear itself.
