There is a city of time in everyone's heart, which is built up with all the time spent loving a certain person. It can only accommodate yourself and a certain person.
For Fang Su, it took ten years to build a city of time for Lin Molei that he thought was indestructible, but in the end it was so vulnerable.
Lin Mo is the only scenery in Fang Su's City of Time, and Fang Su himself has unknowingly become the only scenery in the City of Time in someone's heart. Some people love Fang Su, some love Fang Su, some suffer from Fang Su, and some suffer for Fang Su.
One person's unilateral dedication to feelings is always incomplete. Only two people's mutual dedication can be happy. In the end, who is the person who builds the city of time with him?
