It started to rain, and Wu Li remembered that day when the heavy rain trapped everyone in the subway. People wanted to escape, but they were already trapped, and her boyfriend Gu Tong should be waiting for her to leave the station at the train station.
But Gu Tong didn't know that Wu Li lied to him that day, and she didn't go on a trip, but was still at work.
Gu Tong didn't know that Wu Li was trapped in the subway and was still waiting outside the train station until the staff announced that many trains were delayed and asked them to go back separately.
Intention: later
