I still remember the face, but forget the voice. Kang Yang said this to everyone.
Kang Yang met Shen Kan at a high school class reunion, and they were polite to each other, as if they had been ordinary friends for many years. While chatting and laughing, they shared with each other the changes after two years of graduation. When asked about Kang Yang, "Me? I am a freshman."
On the way home, she received a friend request from Shen Kan - "You still haven't talked about it for a year." Kang Yang agreed and watched the traffic lights change along the way in the taxi.
