He is a track designer and says the shortest path between us is minus infinity.
I am a stone digger, and I have been decoding his heartbeat and brain waves for three years.

Shen Yan, PhD in planetary geology, has both undergraduate degrees.
Others call her "Wild Road", but she doesn't care.
She only cares about the rocks on Mars and her father's words, "Go and see for me."
Gu Shen, an aerospace orbital designer, is a genius boy.
Others call him a "walking orbital computer", but he doesn't care.
He only cares about the detector not crashing, and the secret that has been hidden for three years——
He didn't dare to fly, not because he was afraid of death, but because he was afraid of never seeing her again.
The first time we met, in the uninhabited land of the Northern Desert.
He said with a cold face: "Your data is wrong."
She smashed the core collected in 37 days and said, "See for yourself."
Later he taught her orbital topology and she taught him how to read Martian rocks.
He used his body to protect her in the sandstorm, and his arms were covered in blood.
She secretly set a screenshot of his brain waves as wallpaper in the late-night laboratory.
On the day the data was tampered with, the entire project team was suspicious of her.
Only he violated the confidentiality agreement and re-run the track with his own hands.
"Just find the truth and leave the rest to me."
The night before launch, the detector lost contact.
He climbed up the tower alone and repaired it manually.
She looked at his vital signs in the charging hall, her palms all sweaty.
When he came back, she rushed to hug him in front of everyone.
On the day of the national live broadcast, he said:
"Thanks to a geologist for teaching me how to look at time."
Everyone in the barrage is guessing who it is.
Only she knew that he was talking about "my wife".
——
Later he proposed, not with a ring.
It is a slice of Martian meteorite, with a line of words engraved under the slice:
"I spend every second of my life thinking about you."
She drew a smiley face on pH test paper and replied to him:
"Neutral, neither acid nor alkali, just right. I like it."
Concept: "Letter from the Deep" is not a simple sweet pet story. It writes about: the persistence of an ordinary person, the mutual healing of two injured souls, the silent support of the fathers, and the idealism that in this utilitarian era, there are still people who are willing to spend their lives for a distant stone. The depths of time are measured in billions of years, but human love and courage last longer than the depths of time.
