Qiao Xi, a task executor for the Spacetime Administration, enters a novel world with a truth-telling system to complete her final plot-repair task. She originally wanted to push key characters back onto their predetermined track, but due to system restrictions, she frequently blurts out the truth, causing numerous unexpected laughs in lifestyle reality shows and daily tasks. Through repeated shared experiences, she and Yu Sinian—an actor who appears distant but is gentle at heart—move from mutual guardedness to tacit collaboration, gradually coming to understand the meaning of trust, responsibility, and companionship. Using book-crossing, systems, and reality shows as comedic elements, the work tells a lighthearted romance story of two young people with contrasting personalities who help each other, grow together, and harvest genuine affection.
