Had very clear set-up with multiple moments showing Miu be into Sousuke (for example, someone says "when you think of someone you like, you get more power!" and Miu immediately thinks back to a time she was concerned for Sousuke in battle, and the goes "Why did I remember that!?"). However, they never actually get together despite all the build up.
Miu is explicitly shown to have romantic feelings for Sosuke and Sosuke is oblivious. However it never really goes anywhere beyond hints.
One of them (Norea) was killed just after accepting a proposal to travel the world with Elan.
Spoilers! Norea gets killed right as she is agreeing to El5n's plea for them to escape the war* and run away together instead of laying down their lives as replaceable tools. *(referring to it as "the war" is a oversimplification of the political conflict they're involved in, done on purpose to save time/space for this submission)
(Side note that I think should be taken into consideration in classifying the ship as straight bait: The actual main couple of the show is an f/f couple. They are engaged to be married [Update because the finale just aired today: epilogue shows them now married with their wedding rings on], they both live, & their developing relationship is a main driving force for the plot, in-part because said engagement is a very purposeful Revolutionary Girl Utena reference, because the show's head writer also wrote the novel adaptation of Utena)
[END OF SPOILERS]
So El5n was actually really annoying to watch for most people when he was introduced, but watching El5n and Norea annoy each other was very enjoyable, especially while they were locked in a room together (along with Nika) because any of them being out and about would be inconvenient for the faction each of them had gotten tangled up with.
