In both of these short productions, a woman sees the talent and beauty of a young performer and invests in her success, the proceeding closeness develops into something more.
Both feature opera and homoerotic relationships. However, that is just my personal reading of Yanxi Palace. I would say there are homoerotic subtexts in the drama but it does depend on your own reading.
In both of these short sapphic historicals, the female leads are instantly drawn to each other and whisked into a romance fueled by the others grace and approach to life. But being together requires a test of courage.
