Was there a plot of a woman cross-dressing as a man in modern romance novels? Or was there a female lead that looked very male?

The female lead was misunderstood as a man by many people in the company. There was also a woman who liked her. Later, she had a stomachache (period…). The woman asked her and found out that she was a woman.
The male protagonist also worked here (I really can't remember…), and they contacted each other by letter for many years (maybe 2 or 3 years, or maybe 4 years…). Later, the male protagonist finally confessed and found out that she was a woman (…)
When she got married, the female lead took off her wedding dress and married the male lead in a suit (…). She stabilized (shocked) the audience and made it into the newspaper…
After that, she traveled around the world. Anyway, she always carried her marriage certificate (or ID card?) To show his identity…
That's it. If anyone has any impression of it, please help me think about it…
Was it a little old, no one had seen it before…

Answer 1

I recommend 'I like you a little more every day' to you. The female lead of the novel, An Xiaomi, had to wear men's clothes for some reason to hide her identity and live a boy's life on campus. However, she had always been pursued by the male lead, Gong Qianhan. The male lead had expressed his feelings for her, but the female lead chose to avoid him in order to avoid being criticized. However, after a few interactions, the male protagonist realized that she was very similar to the girl he liked. This is a 1v1 love story. The female protagonist is strong and not a white lotus. The male protagonist is affectionate and has no ex. I believe you will like it. I hope you like my recommendation.
