Hi, I'm trying to locate an old manga/or manhwa that was about a hidden royal heir. To protect and hide him, he was taken in by a madam/woman that runs a brothel. He grows up disguised as a woman and works behind the scenes plotting to take back his throne. He falls in love with the daughter of one of the generals that betrayed his parents. The girl also happens to be engaged to his half-brother. Who in turn is also smitten with him, not knowing the male lead is in disguise as a woman. Anyway, the guy becomes obsessed with obtaining the main male lead. And hates the girl he's engaged with. The story is not yaoi. Because the male is only in love with the female lead. And the setting is in a historical time frame. I think this might've been published sometime between 2016-2018. I'm not sure if this is on webtoon, but I think it used to be on that website.

Twelfth Night (Muryu)?
