Back when I had just started watching Asian dramas, I watched The King's Affection and Love in the Moonlight, both Korean dramas. Maybe they qualify as crossdressing girls media. I liked them, but I was left with a bit of dissatisfaction after watching them one after the other, because in the end they were, as you mention in your post, pretty heterosexual, and this made me seek other kinds of stories. I'd also love to see trans versions of this.

I really, really liked Rookie Historian Goo Hae Ryung, and now I'm curious about the other dramas you mention here. I'm always looking for good dramas to watch.
