Lin Yue, an ordinary company employee, has a crush on Gu Yunshen, an elite of the company she works with, but an accident causes her to travel a hundred years into the future.
Here, humans rely on an armor called the "Heart Armor" to fight against the erosion of time and space, and the person who can awaken the strongest armor, the "Armor of Time", is actually a long-dead hero in history-Gu Yunshen.
In order to return home and uncover the truth behind the hero's death, Lin Yue approached the cold name in the future textbook as a "historical researcher". However, she discovered that the Gu Yunshen in front of her was kind and strong, but he was insulated from "love".
"Love is a weakness that will make people irrecoverable." He firmly believed.
Lin Yue guarded him silently, using the warmth from the past to melt his frozen emotions bit by bit. When the crisis of world destruction came, Gu Yunshen finally broke the taboo for her, and the armor bloomed with unprecedented light.
However, this light also illuminates a cruel truth: the hero's sacrifice is the starting point of time travel. Does saving the world mean losing him forever?
