The Watch That Fell From the Sky

The Watch That Fell From the Sky Plot:

Su Xiaoxia, an invisible intern at an advertising company, is hit by a "watch that fell from the sky" while staying up late revising a proposal. She discovers the watch can show her 1-hour-ahead fragments of the future—helping her crush, design genius Lin Chuan, defuse a client's刁难, saving her overtime bestie from a delayed subway… But every use makes her lose a precious memory: first, she forgets her mom's signature dish, then she can't recall her first meeting with Lin Chuan. When she uses the watch to stop Lin Chuan from leaving due to his ex-girlfriend's reconciliation plea, the watch suddenly alarms—turns out, the watch is a "regret medicine" sent by her future self, but in 7 days, she must choose between "retrieving all memories" and "holding onto the possibility with Lin Chuan".
