Looking for ancient love letters, written by women to men, expressing the feeling of love at first sight. The length should not be too long.

I strongly recommend " Finger Note " to you. The novel is about the heroine picking up a love letter at school. The content of the love letter makes her empathize with it and also makes her curious about the person who wrote the love letter. Although this novel was a short story, the plot was tight and the writing was beautiful. It also perfectly expressed the love at first sight of the female lead. It was worth reading! I hope you will like my recommendation.😘
