It's my own imagination for practicing writing. I didn't give the protagonist a name. In the article, I call him the male protagonist, the female protagonist, etc. Directly.
The male protagonist is Jin Yiwei, and the source of his idea is a video of a wife cutting out an embroidered spring knife.
I won't say too much because the text is pitifully short.
Concept: There are always invisible barriers between classes, so Romeo and Juliet are so precious
