Gears of Destiny**: On two nights where time and space intersect, seventeen-year-old Qi Muze was hit by an athletic student who climbed over the wall while checking in. In the confusion, he bit off the opponent's ring. After meeting again in the archives ten years later, the gears of fate began to turn.
- Undercurrent: Qin Liang parachuted into the archives as deputy director and started a workplace game with Qi Muze. The memory flashback triggered by an eagle ring allows the two to glimpse the outline of the past in the dust of the archives.
- Secret Chase: Qi Muze used "confession tactics" to cope with work pressure, but discovered the crescent-shaped scar on Qin Liang's index finger while working overtime late at night. The eagle ring was hot in his suit pocket, and the "Woodpecker Man" whose face he had not seen clearly ten years ago gradually became clear.
- **Heart to Heart in Heavy Rain**: Trapped in the archives on a typhoon night, Qi Muze's ravings when he had a fever revealed the past. Qin Liang stared at the tooth mark on the ring that had not healed for ten years under the emergency light. The "dog tooth flower" that he had missed in his heart was washed away by the heavy rain that had been hidden for many years.
Intention: If life were just like the first time we met
