I'm still keeping those two in mind and working on it (often as a distraction when I get depressed about my current work situation) - though most probably there will never be a story. I'm not good at stories. I can make up characters and individual scenes, but I can never think of a proper plot.
It's a bit of a shame, really. While cleaning up my parents cellar recently and sorting through my old stuff I found a folder full of material about the U.S.S. Phoenix: I made up a Starfleet ship, with the whole bridge crew, their backstories and even drawings. But I never could think of a good story, so that went nowhere.
This song kind of represents the atmosphere I'm having in mind for Han and Li:(Love this song, but unfortunately it's not available as a download in Germany. It's the ending of the anime Uragiri wa Boku no Namae wo Shitteiru.)
