Three days before Ding Qingya's wedding.
Song Qi dialed the phone number that was once familiar but now unfamiliar: "Hey, do you want to meet? I heard that you are getting married."
In the coffee shop on the corner of the street, Song Qi wore light makeup, smart short hair, and a slim-fitting khaki professional suit as always. She came half an hour earlier than agreed, just like their previous dates.
The coffee was already a little cold. In the first two years of working, she basically had a cup of black coffee every day, with milk and no sugar.
Concept: You and I are both variables, so how can we take the statement "I love you" seriously?
