Thirty-five-year-old advertising creative director Wang Tianxuan thought he had everything figured out - until he met his first love Lin Xiaoyue, whom he had left without saying goodbye fifteen years ago, at an old city renovation project meeting.
She was the most difficult architect on that project, insisting that every old brick be preserved. He is the lobbyist hired by Party A and is responsible for making her "recognize the reality." But when she turned around, time collapsed. The unfinished confession in the library on that rainy night, and everything that I thought would last forever when I was young ended hastily, but it turns out that it has never really passed.
Now there is a ring mark on her left ring finger but no ring. He has a current girlfriend who is talking about getting married. Old neighborhoods need to be demolished, theaters need to be renovated, and the decency of adults needs to be maintained. But when a heavy rain trapped them in an old theater that was to be demolished, the truth about their separation was finally revealed - it turned out that they had all been played a cruel joke by their youth.
"If you had it to do over again now," she said softly in the darkness, "would you choose me?"
Wang Tianxuan knew that this time, his answer could not be delayed for another fifteen years.
