Cheng Xiao ran out of the house angrily, it was pouring rain outside, Cheng Xiao had nowhere to go, so he called Xia Zhi, who knew she had a flight mission. Cheng Xiao sat outside alone for a long time, cold and hungry, she saw a bar still open on the street, so she opened the door and went in. The owner of this bar is a retired pilot and is good friends with Xie Zetian, who often comes here as a bartender. Xie Zetian saw Cheng Xiao with a sad and decadent face, so he quietly called Gu Nanting.

Gu Nanting originally came to pick Cheng Xiao back, but she fell asleep lying on the table in the bar. The bar owner was afraid of waking her up, so he told Gu Nanting not to wake her up, so he let her sleep here. Gu Nanting could only put his coat on Cheng Xiao and ask the waiter to take care of it. When Cheng Xiao woke up the next day and found the clothes, he knew that Gu Nanting had been here.
