This popped up in my recommendations, was pleasantly surprised: Roughly translated title: 【San Wu x Zu Ya Na Xi】Female Fuma丨She and her in front of the ornamented candles (The "Treacherous Waters" X Huangmei Opera story you've never heard of) (Note: Treacherous Waters is a famous martial arts drama that focuses on loyalty and justice) Dialogue in the beginning (roughly translated): Princess: "Fuma, was the scenery beautiful along the way here?" Fuma: "The rivers and mountains were indeed beautiful, a natural beauty that lies in this world. Princess: "Then, Fuma....how beautiful is the princess inside the bridal chamber?" Fuma: "Ah? This....this...." So for context: This is a collab cover of a song from a Huangmei Opera play that's called "Emperor's Female Son-in-law" but it's more accurate to translate it to "Female Fuma". This is how the story goes: MC crossdresses as a man to enter the imperial exams and somehow, she ends up getting first place. The emperor is so impressed that he decides to marry MC to his daughter, the royal princess. On the wedding night, MC reveals her true identity to FL. Now, here's the catch to this story, you could say this is like the ancient Chinese form of Yuri bait, because the MC actually does all this for.....her imprisoned fiance....a man whose name I've long forgotten. It ends with a BG ending, with the MC reunited with her fiance and the FL ends up with some other noble dude. Leaves quite a bitter taste in my mouth. There are also two TV shows about this story as well, the newer one was made in 2001 and called "New Female Fuma" (wow what a creative title) and has a lot more GL moments, but only tiny crumbs so I don't recommend you watch it. Now, this cover/animation basically rejects this BG ending and pulls a reverse card by going for the GL route. When they say it's the "The 'Treacherous Waters' X Huangmei Opera story you've never heard of", I believe they mean that in their version this is like a revenge story where MC enters court to seek justice and the princess and MC are the true CP. Cute art and beautiful vocals, take a look if you have the time.
