Lin Xingwan's youth was like a secret program running in the background.
During her three years of high school, Jiang Yu was the "core code" that was out of her reach, the source of all her abnormal heartbeats, and the "fatal bug" that she dared not touch. She thought her secret love was a "system error" that no one knew about.
It wasn't until they reunited in college that she discovered that the cold and distant computer guru seemed to have laid a foreshadowing in her world.
From campus to workplace, from "borrowing" to "borrowing for life", he used the unique romance of programmers to reconstruct her world bit by bit.
It turned out that all the unexpected encounters were his long-planned plans.
All system abnormalities are heartbeat signals sent by him.
When the bug was fixed and the program ran perfectly, he held her hand and whispered in her ear: "Wanwan, in my world, you are never a mistake, but the only whitelist."
