On the night of her 30th birthday, Lin Xun found the butterfly hairpin in the old box - a gift given to her by Xiaoying, a transfer student in fourth grade. She had not seen it since Xiaoying disappeared in fifth grade. The moment her fingertips touched, she returned to the autumn of 1998, seven days before Xiaoying disappeared.
She became a "trace repairer" of time. With a vague memory of future news, she must reverse the outcome within seven days. The young film police officer Chen Zhengyang became her only ally, and the two raced against evil in the passing time.
After traveling several times, several unsolved cases were quietly rewritten. When she returned to reality, the missing person was alive, the injustice was revealed, and her life seemed to be being repaired bit by bit.
It wasn't until the fifth autumn that she began to receive "gifts" that spanned time and space:
Withered lily petals, a yellowed class photo, and a handwritten card——
"You bridged every rift except mine."
Only then did she understand that when you fill in the gaps in time, there will always be something that will quietly crawl out of the gaps.
Concept: Old cases are corrected in the sun, new crimes breed in the shadows.
