After I Met You movie version

Thank you for letting me meet love, and thank you for letting me meet a better myself. On the streets of ancient Rome, the ordinary Huang Manman (played by Huang Yao) accidentally met his idol Peng Boyang (played by Liu Xun) who was completely different from him. The two people, who had no contact with each other, staged a romantic and surprising love journey in Rome, and the whole city was full of love. But the development of things was not as good as they imagined, and real life brought the two of them back to the starting point. Time has passed, do they still remember the promise they made to each other on the streets of Rome that day?
