It's been a long time since I started writing. This time, I really started writing. I wanted to connect several scattered short films together to complete a feature. At least that was the original intention. But then I suddenly thought of something, something that puzzled me and was worth thinking about, and that was what two people were doing before they met. They had met on the same occasion several times in their lives, but they didn't know each other, and maybe they wouldn't have thought of those fragments when they really met. Not only that, how many opportunities are needed for acquaintance is also a question. Among many acquaintances, how difficult it is to choose someone to fall in love with, and what kind of situation it will be. I want to speculate and understand.
