Bai Xing is 29 years old and works as a project director in a film and television company. His life motto is "You only allow yourself to make a mistake once." She once almost ruined her career because of an out-of-control relationship. She spent three years rebuilding everything and completely arming herself into a "person who will never look back." A new project is coming, and the partner is the person she least wants to meet: Ye Qianlin - the old lover who caused her the most embarrassment back then is now the most difficult investor representative. They fought fiercely at the negotiation table, had to fight side by side during project crises, and unexpectedly said things they had never said clearly at the night snack stall. Bai Xing never regrets, but one early morning he discovered: There are some things in the past that you didn't care about, but you just chose not to stay there. And to love someone, you don't have to wait where you are. You can also start from scratch and take a road that no one has ever walked before.
